Abstract

The present subject matter relates to methods of high-speed analysis of product samples. Light is directed to a portion of a product under analysis and reflected from or transmitted through the product toward a plurality of optical detectors. Signals from the detectors are compared with a reference signal based on a portion of the illuminating light passing through a reference element to determine characteristics of the product under analysis. The products under analysis may be stationary, moved by an inspection point by conveyor or other means, or may be contained within a container, the container including a window portion through which the product illuminating light may pass.

Claims17

Dependent claims

A method for high-speed analysis of product samples, comprising:

illuminating at least a portion of a product with light at an inspection point;
providing a plurality of light sensitive detector, the detectors producing outputs based on received light;
directing light from the product portion toward selected of the plurality of light sensitive detectors through at least one multivariate optical element, the light from the product portion carrying information about the product portion;
directing at least a portion of the product illuminating light toward one of the plurality of light sensitive detectors through a reference optical element;
and
analyzing the signals produced by the detectors, the analysis being based on a comparison of the signals produced from light passing through the at least one multivariate optical element and the signal produced from light passing through the reference optical element
