Optical Inspection of Polymer-Based Materials

Abstract: 

An optical inspection system for using laser-induced luminescence to detect deterioration of a polymer-based material. The inspection system comprises an excitation means for illuminating a specimen of the polymer material to cause it to produce fluorescent radiation. The spectral representation of the fluorescence produced by the specimen is compared to the spectrum of a reference sample of known quality in order to obtain an indication of the physical characteristics of the specimen.
