Multispectral analysis of wheat grain samples
The VideometerLab 4 from Analytik (Cambridge, UK) is a multispectral imaging and automated visual measurement system designed for fast and accurate determination of surface colour, texture, shape, size and chemical composition.
The easy-to-use instrument 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. A new Autofeeder option allows pre-built calibration models to be loaded and applied to larger sample sets for automated analysis.
Traditionally, non-destructive investigation of materials with non-uniform colour and texture can be difficult, tedious and expensive. Conventional techniques such as NIR spectroscopy only measure a single point or average over a fixed area and do not give an objective overall assessment of visual quality.
Studies show that VideometerLab 4 is as accurate as a test panel with significantly higher repeatability, removing subjective judgement. Specific areas of special interest such as shape, size or texture can be studied automatically.
Drawing upon customer feedback the VideometerLab 4 is the latest version of this popular vision-based lab analyser. The system integrates illumination, camera, and computer technology with advanced digital image analysis and statistics to provide a rapid assessment of uniform and non-homogeneous samples.
Using strobed LED technology VideometerLab 4 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.
