On-Line Process Monitoring

Hyperspectral imaging can be used to monitor the chemical uniformity of many industries' products, from pharmaceutical blends and transdermal films to semiconductor materials to food and agricultural products. It allows for quality assurance during production and a faster product release time. In comparison with traditional quality measurement via sampling and using destructive testing, hyperspectral imaging offers a non-contact, non-destructive method to quantitatively evaluate the spatial dispersion of chemical components within a product.

How it works: One can perform on-line process monitoring by implementing a hyperspectral camera directly over the production line. The 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 product at a time and as the product moves underneath the camera, 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 product.

Middleton Research will work with you to develop a hyperspectral system that is optimized for your specific application. We provide individual system components and/or consulting to integrate a specific system complete with camera(s), illumination, and software to meet your needs.
