Problems solved by technology

This paper presents a calibration method for the parallelism of the visual axis, but this method cannot satisfy the adjustment of the mirror when the mechanical pointing to the zero position of the periscope follow-up mechanism, nor can it be applied to periscopes with different calibers. The installation and adjustment of the reflector of the tracking mechanism, and the application of the roof prism will introduce a large error, the tooling for placing the pentaprism is complicated, and the machining accuracy of the tooling will also affect the accuracy of the installation and adjustment

Embodiment Construction

[0031] In order to solve the requirement of high precision for the installation and adjustment of the reflector of the periscope tracking mechanism, make full use of the high-precision angle measurement and self-collimation precision of the theodolite, and the advantages of being able to flexibly establish a coordinate system, this invention proposes a high-precision submarine This method is based on the self-collimation and active inter-pointing functions of the theodolite, and establishes a horizontal and vertical coordinate system based on the geodetic level and the installation reference plane of the periscope tracking mechanism. The theodolite is used as an energy A collimator with large range and high precision deflection azimuth and elevation angle, specially designed a set of tooling to make the installation reference plane of the periscope tracking mechanism vertical to the ground level datum, using three theodolites to establish a coordinate system to install and adjus...

Abstract

The invention discloses an adjustment method for reflectors of a periscopic type acquisition and tracking mechanism. According to the method, three theodolites are used for building coordinate systems to adjust the reflectors of the periscopic type acquisition and tracking mechanism, one theodolite serves as a datum optical axis through an installation datum plane, the datum is transmitted to the other two theodolites according to a geometrical optical principle to build one coordinate system so as to monitor the position of an orientation reflector in real time, then the position of the orientation reflector is adjusted well, the orientation reflector is locked and fixed, the position of a pitching reflector is monitored by rebuilding one coordinate system of another theodolite, the depth of parallelism of received light beams and emitted light beams of the periscopic type acquisition and tracking mechanism is greater than one thousandth according to the technical index requirement, and light tangency is avoided.

Description

technical field [0001] The invention relates to a mirror assembly and adjustment method, in particular to a high-precision periscope tracking mechanism mirror assembly and adjustment method, which belongs to the field of laser communication. Background technique [0002] In recent years, laser communication technology has developed rapidly, and the PAT (Pointing, Acquisition, Tracking) system is the key for laser terminals to realize inter-satellite links. There are mainly: periscope type, universal joint type, and swing mirror type. The periscope tracking mechanism is characterized by small moment of inertia, large rotation range, small motor power, simple locking device design, moderate mirror size, but complex assembly, large encoder motor bearing structure, and difficult mirror film system Therefore, the adjustment accuracy of the reflector is the key to the parallelism of the sending and receiving beams of the periscope tracking mechanism, which has a profound impact o...
