Abstract
The possibility of visualization of anomal crystallization zones in polymeric material intermediate products by using an optical-electronic model of a test bench has been shown. The visualization is necessary during following production stages: the periodical technical process control, the sample control and the waste rejection. An original scheme of the model construction providing a solution of the raised problem by means of a minimal device composition has been suggested. The model experimental researches for different light sources of the visual and infra-red spectral ranges and different illuminators have been carried out in order to determine an influence of the lighting conditions and light spectral composition on the heterogeneity image quality. The results have permitted to formulate demands to the light source and forming illumination system of the test bench reasonably. The main attention has been given to the diagnostics of the heterogeneity near the top of the intermediate product that is the most typical, difficulty measured, and that exerts essential influence on the product quality. The investigation results for two intermediate product groups of different firms are given. A comparison method of the crystallization zone sizes with the technological norm has been suggested.
