Layout of the flatbed scanner elements (without the optical system elements): 1-light source, 2-object, 3-fixed glass, 4-photodetectors, 5-scanner carriage; SL and MRL are the scattered and the specularly reflected light, respectively. A flatbed scanner that is a relatively easy-to-use device for reading images and texts from printed materials can serve as an excellent tool to obtain and subsequently analyze object images, i.e., for contactless non-invasive diagnostic scanning. Let's emphasize the value of the scanner as an instrument for physical research: the scanner is a complete experimental setup for observing the scattered light from the flat objects in the visible wavelength range; the scanner has 'flat' optical characteristics as opposed to devices with spherical or cylindrical optical systems (cameras, video cameras, microscopes and so on.) This allows to eliminate the errors arising from controlling the uniformity of the properties of studied flat objects; a non-contact scanner reads/scans the information 'line by line' in contrast to the serial line reading in most contact scanning technologies of various modern microprobe methods (such as profilers and various scanning microscopes, e.g., an

... 2 The instrument 2.1 Overview of ICE-CAMERA ICE-CAMERA is a flatbed scanner (Zheleznyak et al., 2015) whose operating principle is the same as that of ordinary flatbed scanners in offices. In the case of ICE-CAMERA, it is specially designed for observing polar precipitation in the harsh environmental conditions of Concordia station (Fig. 1). ...
Studying precipitation at very high latitudes is difficult because of the
harsh environmental conditions that limit the external activity of humans
and instruments, especially in the polar winter. The direct monitoring of
ice crystal habits and size distribution in Antarctic precipitation is
important for the validation of the algorithms used for retrieving
precipitation from ground-based and satellite-borne radar instruments and
for the improvement of the climatological modelling of polar areas. This paper
describes an automated device (ICE-CAMERA) specifically developed for the
imaging, measurement, and classification of ice precipitation on the
Antarctic high plateau. The instrument gives detailed information on
precipitation on an hourly basis. The article provides a description of the
device and its image processing software. Starting in 2014, the instrument
has operated almost unattended all year round at Concordia station, Antarctica (75∘ S, 123∘ E, 3220 m altitude).
... The use of a flatbed scanner was inspired by the tool ScanLag (Levin-Reisman et al., 2010), used to track the size of solid colonies in agar plates. In our case, the adequacy of flatbed scanners to capture OD data is based on the geometry of their optical system: it is such that the light that is specularly reflected from the sample does not reach the photosensors, so the scanner can be used as a physical instrument for recording the scattered light (Zheleznyak and Sidorov, 2015). In the flatbed scanner used during this investigation, a linear array of LED lights illuminates the sample while photosensors (of type LIDE, an improved version of contact image sensors) capture the image. ...
... It should be noted that the current version of ScanGrow has been configured to use scanned A4 size-images at a resolution of 300 dpi, since all images were acquired with an economical scanner coupled with contact image sensors. As can be inferred from Figure 1, increasing the quality of the well images could be attained by using a different flatbed scanner of higher resolution or one that uses an optical system of a charge-coupled device (Zheleznyak and Sidorov, 2015). Besides, all the acquired images presented an inherent lack of optical focus due to the skirts of the microplates elevating the bottom wells away from the scanner surface. ...
Monitoring the growth of bacterial cultures is one of the most common techniques in microbiology. This is usually achieved by using expensive and bulky spectrophotometric plate readers which periodically measure the optical density of bacterial cultures during the incubation period. In this study, we present a completely novel way of obtaining bacterial growth curves based on the classification of scanned images of cultures rather than using spectrophotometric measurements. We trained a deep learning model with images of bacterial broths contained in microplates, and we integrated it into a custom-made software application that triggers a flatbed scanner to timely capture images, automatically processes the images, and represents all growth curves. The developed tool, ScanGrow, is presented as a low-cost and high-throughput alternative to plate readers, and it only requires a computer connected to a flatbed scanner and equipped with our open-source ScanGrow application. In addition, this application also assists in the pre-processing of data to create and evaluate new models, having the potential to facilitate many routine microbiological techniques.
... (Non-linear, first-order exponential) calibration curves for all three colors (red, blue, green) of a single pixel of a color image were made demonstrating sensitivity limits as low as 0.01 µg/ml. ZHELEZNYAK and SIDOROV [16] used a flatbed scanner to measure scattered light from samples in order to estimate surface roughness (down to 2 nm rms roughness, with 3 to 10 µm lateral resolution), scratches and defect densities, including their position, shape, and size; and bowing or surface curvature, of various metal, glass, semiconductor, and dielectric specimens. ...
... The rotation angle of the rotor is equivalent to the wind-direction angle. Thus, an optical scanner [17] is used, with its internal light source connected to the fiber anemometer, to monitor the wavelength shift in the FBGs for obtaining the corresponding shaft angle variation and detecting wind direction. being rotated by the rotor, the central wavelengths of the two FBGs are shifted and display sinusoidal variation with a phase difference of 90° between them. ...

Thus, an optical scanner [17] is used, with its internal light source connected to the fiber anemometer, to monitor the wavelength shift in the FBGs for obtaining the corresponding shaft angle variation and detecting wind direction. For the wind speed experiment, the frequency diagrams obtained in the oscilloscope with four rates (200, 400, 600, and 800 rpm) are displayed in Figure 7. Figure 7 indicates that the accuracy of the overlapped frequency can be obtained. ...
A novel fiber anemometer based on two pairs of fiber gratings is experimentally demonstrated and can simultaneously detect wind speed and wind direction. One pair of gratings, which are separated by 90° in space, is fixed on a small stainless steel pipe driven by a rotating disc for measuring the wind-direction angle. The other pair is composed of a sensing and a matched grating. The frequency of the spectrum-shifted of the sensing grating to overlap with that of the matched grating is employed for determining the wind speed. The errors in the wind-speed and wind-angle measurements are experimentally demonstrated to be less than 1%. The proposed fiber anemometer with a simple and durable structure can be applied in wind-powered electricity generators.
... Hence, it is vital to study the effects of this process on the geometric accuracy and visual quality of the original image. Several studies have looked into the radiometric characteristics of flatbed scanners, ( [16] [17] [18] ). The radiometric performance of scanners could be affected by noise level, linearity, dynamic range, effect of illumination variation, and presence of artifacts or blemished pixels [19]. ...
Analog documents and scanned digitized files are now considered equivalent in legal contexts, and the widespread supply of multi‐functional printers has led to a surge in the use of scanned documents. With image editing tools, there has been more cases of forgery involving scanned files. This has highlighted the importance of integrity and authenticity verification of scanned documents submitted as court evidence. Extensive studies have been conducted on source scanner identification and detection of alteration in scanned documents. Past research usually relied on machine learning with Support Vector Machine (SVM) and Convolutional Neural Network (CNN), and was focused more on images rather than text documents. Brightness variations are produced depending on the repetitive arrangement and relative intensity of light sources, and such patterns can be clearly observed in scanned images by the Charged Coupled Device (CCD) type flatbed scanner. The separate image module of the Contact Image Sensor (CIS) also leads to characteristic brightness variations. To extract and enhance these brightness variations, image processing techniques such as separating color channel and adjusting gradation and contrast are applied. The proposed method was tested on five scanner models, and the results confirmed that each scanner had unique brightness variations. This study is the first to extract brightness variations as a unique characteristic of each scanner model and recognize the potential of brightness variations in source identification and manipulation detection. A major advantage is that brightness variations are physical, robust, and visible. The research will be expanded with multicolor documents, counterfeit documents, and text‐independent detection.
Texture analysis is an emerging field; and it is just beginning to integrate with radiology. Carrying out research with thousands of images can be overwhelming, without an effective and efficient sorting algorithm. The aim of this experiment was to develop a sample selection-elimination protocol for a large research project seeking to compare fetal 1.5- tesla versus 3-tesla magnetic resonance images. Firstly, we had to find optimal methods for image selection. In a compiled database of 1.5-tesla and 3-tesla images, we began by manually selecting sequences based on discernible-anatomical structures (ventricle, thalamus, grey matter, white matter). Then 1.5-tesla and 3-tesla image batches were categorized into two groups based on gestational age (i.e. first group: 20-28 week; second group: 29 week). The final stage was sample elimination by variance and by real bit-depth – that is the actual stored bits which correlate with the measured mean, not the expected mean derived from allocated bits reported in the image metadata. Though both 1.5-tesla and 3-tesla images were formatted as 16-bit digital imaging and communications in medicine, a maximum of 12 and 16 stored bits were measured in 1.5-tesla and 3-tesla respectively. This finding was crucial for fair selection and therefore ideal for assessment of the quality of 1.5-tesla versus 3-tesla – rather than simply relying on visual appearance. Stored bits were constant in both gestational groups of the same magnetic resonance modality but not variance. Artificial intelligence can further enhance sorting of images for comparative studies. Despite the current constraints and limitations, we recommend further feasibility studies, software development, clinical trials and eventually more substantial integration of "radiomics" (radiology and computer science) in medical practice.
The aim of the presented work was to develop and validate a novel high-throughput rapid Folin-Ciocalteau assay for the quantification of reducing capacity of foods based on image scanner (Image-F-C assay). The original rapid F-C assay using a 96-well plate was improved by adding a neutralization step that stabilizes the formed color, enabling image acquisition using a flatbed scanner. Although the scanner has been already used in other analytical applications, no analysis has been reported regarding the effect of the scanner model, the plate orientation or the reaction volume. In the present study, we establish that the mentioned parameters do affect the linearity and precision of image based Folin-Ciocalteau assay, and provide the optimal scanning conditions for the analyzed scanner models. Euclidean distance calculated from R (Red), G (Green) and B (Blue) values was chosen, based on linearity and sensitivity, in order to quantify the reducing capacity. An in-house program using free ImageJ macro language was written to calculate automatically the RGB values of each well. The Image-F-C assay is linear within the range of 0–20 mg L−1 of gallic acid (R2≥0.9939). We compared reducing capacity values from real samples quantified by the image F-C assay and by a microplate reader and an inter-day relative standard error<8% was observed. Bland-Altman and correlation analyses showed that there were no significant differences between the two methods.
