Abstract

Optoelectronic sensor of 2D angular displacements consists of transmitter head with diode lasers as a light source and detection head. The detection head consists of focusing lens, and, placed in its focal plane, 2D position sensitive detector. The current signals collected by electrodes of detector are transformed in analog signal processor to obtain the x and y coordinates of spot center position signals with respect to the center of photosensitive area. The x and y position values divided by focal length represent the coordinates of angular displacement of detection head with respect to the axis of transmitter beam. There was determined the calibration curve of the sensor. The typical results of angular displacement measurements were presented and discussed.
