Influence of array photodetectors characteristics on the accuracy of the optical-electronic system with optical equisignal zone

Abstract

In this paper we attempt to assess the possibility of applying the array of photodetectors and digital information processing in positioning systems based on optical equisignal zone. The basic theoretical information about working principles of the system with equisignal zone and the formation of the base direction are listed. The influence on the accuracy of the positioning system some parameters such as the number and size of the array elements of the receiver, capacity analog-digital converter, aberrations of optical elements are researched. The possibility of registering the angular displacements (reversals) of the controlled object by using the developed system is shown.
