Abstract

The optical mechanical system of laser communication has the characteristics of compact structure, highly integration, and multi optical axes integration. The consistency between transmission and reception, divergence angle, and wavefront of the optical telescope of the system are very important indicators. In response to the above difficulties and characteristics, this article conducts research on computer-aided adjustment, fiber optic coupling, and transceiver consistency testing. Currently, coaxial and off-axis optical telescope aligning technologies, high-precision fiber optic coupling debugging technology, and turntable linked space optical path transceiver consistency assembling technology have been formed, which can achieve the target requirements of transceiver consistency of 3μrad and system divergence angle of 30μrad.
