Optical Angular Displacement Sensors

P. 312-315.
Alexander L. Tuv, Yury I. Gudkov, Vladimir N. Azarov.

The paper is devoted to the research and development of a contactless optical sensor for instrumental means of product quality control. The paper presents results of the study of sensitivity of incoherent optical OTDR type sensors to the angular displacement of the reflecting surface. The results of experimental studies of the transfer characteristics of the sensor with transceiver modules of various configurations are presented. Variants of the structure of the measuring channel of the sensor to obtain the maximum range of measured angles are offered. The influence of non-informative parameters on the measurement results is analyzed. The results of mathematical modeling of the angular displacement sensor based on the laws of geometric optics are presented.
