OPTOELECTRONIC DEVICE FOR IDENTIFICATION AND FLAW DETECTION Russian patent published in 1998 - IPC

FIELD: instrumentation, flaw detection, identification and analysis of liquid and gaseous substances, for instance, motor fuels by octane number, percentage of sulfur, cetane, cancerogenic components. SUBSTANCE: base radiation cell 7 is filled with gasoline with known octane number and known chemical composition. Tested gasoline is poured into working radiation cell 6. Light formed by source 1 and optical system 2, 3, 4. 5 passes tested and base products, light guides 10, 11 and hits slit diaphragm 12. Since output butts of light guides 10 and 11 are spaced apart so two diaphragmed light fluxes are formed across output of diaphragm 12. One of them corresponds to base product and the other one to tested product. Optical fluxes hit through lens 13 dispersing element 14 which disintegrates each flux into set of spectral bands by wave lengths entering radiation source 1. Sets of spectral bands is projected by lens 15 on to matrix photodetector 14. Signal of photodetector matrix is processed by device 17. In same manner gasoline or any other oil product may be identified and analyzed for content of sulfur and other components. In this case only processing programs should be changed. EFFECT: enhanced working reliability of optoelectronic device. 3 cl, 4 dwg
