Seeing Objects in a New Light with Multispectral Imaging

Multispectral imaging provides valuable information on the quality and safety of a vast array of materials from pharmaceuticals to raw meat and burned biscuits. The same imaging techniques can be used to measure skin sensitivity to sticking plaster, detect counterfeit drugs and packaging and gain insight into historical artifacts such as mediaeval manuscripts and weapons. This article attempts to highlight some of the newest applications in multispectral imaging, these diverse applications converge as they all in some way have parameters measureable by the technique such as color, texture, gloss, shape and size which when combined give previously unseen information.

VideometerLab 3 Multispectral Imaging System

Analytik Ltd

VideometerLab 3 is a vision-based lab analyser designed for fast and accurate determination of surface colour, texture, shape, size and chemical composition. The easy-to-use system integrates illumination, camera, and computer technology with advanced digital image analysis and statistics. VideometerLab 3 provides a rapid assessment of uniform and non-homogeneous samples by combining information on all of the above parameters automatically in just a few seconds, requiring no sample preparation and leaving the sample intact. Using strobed LED technology VideometerLab 3 combines measurements at up to 20 different wavelengths into a single high-resolution multispectral image. Every pixel in the image is a spectrum and the system can include wavelengths outside the range detected by traditional RGB technology. VideometerLab 3 Multispectral Imaging System Features: Integrating sphere provides very homogeneous and diffuse illumination Multispectral analysis in less than 6 seconds Up to 19 spectral bands in the range 375 nm to 970 nm Fluorescence option available Black and white high resolution CCD camera (2056x2056 pixels) Improved signal-to-noise ratio by individual and automated adjustments of the light intensity in each wavelength band Improved colour determination compared to traditional RGB technology Increased stability due to strobed LED source technology
