Hyperspectral imaging can be used to measure the content uniformity of almost any solid substance including food, agricultural samples, soil, and blends. Measurements can be taken either in a lab or on-line during production to monitor the spatial distribution of components without harming the sample with a high heat load. This is especially important when dealing with food products that must be kept fresh.

How it works: The hyperspectral camera collects both spatial and spectral (chemical) information by employing a push-broom imaging method. As opposed to a staring array, the camera images one line of the sample or product at a time and as the sample moves underneath the camera (or as the camera is moved over the sample), the full image is collected. A full spectrum of each point is saved, resulting in a "hypercube" of data that can be analyzed to identify chemically distinct components and their spatial distribution within the substance. This process is relatively quick and because only one line of the sample is imaged at a time, a high prolonged heat load from the illumination is not necessary.
