Streamlining QC in Food, Feed and Pharmaceuticals using Rapid Multispectral Imaging

18 Jul 2013

Rapid Multispectral Imaging (RMSI) is an emerging technique developed to ensure the quality and safety of food, feed and pharmaceutical materials. Parameters measureable by multispectral imaging such as color, texture, gloss, shape and size give useful quality information on both raw materials and finished products. This white paper discusses a short selection of applications relating to quality issues in food and animal feed production and in pharmaceutical manufacturing, highlighting the benefits of RMSI.

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
