Zenin TI - Photodetector module of optoelectronic control systems for tracking the moving objects T2 - Semiconductor Physics, Quantum Electronics & Optoelectronics VL - 25 IS - 3 SP - 315 EP - 322 PY - 2022 DO - 10.15407/spqeo25.03.315 UR - https://doi.org/10.15407/spqeo25.03.315 AB - An algorithm has been developed for modelling the signals of four-plane photodetector, when moving an axisymmetric light spot along its surface. The form of direction-finding characteristics of photodetector has been calculated for different schemes of illumination of sensitive surface of the detector, which are used in optoelectronic automatic control systems, in particular in the motion control systems for tracking moving objects. Some samples of specialized focusing microprism devices with the distribution of light spot in the focal plane as a central circle with a light ring at its periphery, which are made using diamond micro-cutting based on our simulation results, have been experimentally investigated.
