Abstract
FIELD: measurement technology, instrumentation, precision machine engineering. SUBSTANCE: invention is intended for investigation of method making it possible to enhanced accuracy of test of shape of object and to expand functional capabilities of optoelectronic idea of testing. Proposed optoelectronic method consists in usage of radiation with duration of wave on which absorption of radiation by known contaminant fouling surface of tested article is maximal. Using maximal values of signal amplitudes one makes correction for result of test by addition of thickness of layer of contaminant to result of test. value of thickness of contaminant is found by standard which surface is standard of shape and carries layers of contaminant of known thickness. Spectral characteristics of contaminant can be determined in advance for each particular case of test since brand of used lubricating-cooling fluid - most frequently used contaminant is known by conditions of technological process. Increase of accuracy thus is ensured by input of corrections on basic of spectral characteristics known beforehand. presence of film of contaminant on surface of tested object causes absorption of radiation and change of type of function of measurement conversion of fibre-optical pickup. This change is corrected by correction equal to layer of contaminant. EFFECT: increased accuracy of test of shape of object, expanded functional capabilities of optoelectronic aids of testing. 3 cl, 4 dwg
