Design of structure and control system based on achromatic rotating biprism

Abstract

The achromatic rotating dual-prism beam pointing system is mostly used in space laser communication, which needs to meet the characteristics of small size and light mass. To address the problems of the large size, heavy mass and low accuracy of the conventional beam, this paper uses SOLIDWORKS to build a dual-optical wedge prism model and the structural model of the optical machine and simulates and analyses its environmental performance. The design of the control system effectively improves the beam-pointing accuracy of the whole machine. A reference value is provided for the study of rotating biprism.
