MODELING AND OPTIMIZATION OF OPTOELECTRONIC SENSORS

Abstract

The work considers the optimal design of the optoelectronic sensor. It is characterized by the ability to measure displacements in the millimeter range with submicrometer resolution. The sensor consists of a triangular reflective grating and two fiber-optic probes. The principle of sensor measurement is given. The design of the triangular grating of the sensor was mathematically optimized taking into account the pitch angle of the grating to increase the resolution of the sensor. The optimization method found the global optimum at which the highest resolution is achieved.
