Title: FOOD INSPECTION SYSTEMS AND METHODS
Abstract:
A food product inspection system includes a radiation source that emits high power electromagnetic radiation having a wavelength suitable to illuminate a food product and to generate a photoluminescence response therefrom. An imaging sensor detects the photoluminescence response and generates a photoluminescence image of the food product. A quality detection processor analyzes the photoluminescence images to detect food quality properties of the food product. A sorting system for sorts food products based on a spatial position of the food product in dependence on the detected food quality properties. The system may effectively and efficiently determine the quality of the food product by identifying, for example defective food, thereby reducing labor costs associated with inspecting food products. The use of a processor to process the photoluminescence image allows the use of calibration standards to ensure that food products after inspection all have the same characteristics.
