Abstract

The invention belongs to the technical field of aviation optical equipment, and particularly relates to a method for assembling and adjusting a cassette light pipe. A cassette light pipe installation and adjustment method based on the through-axis principle is proposed. The cassette light pipe can be assembled and adjusted by using the inner focusing light pipe, through-axis tooling and wavefront testing equipment. By designing the tooling, rationally arranging the assembly and adjustment process, only a single component is adjusted each time, the operation is simple, and the assembly and adjustment cycle is short.

Description

technical field [0001] The invention belongs to the technical field of aviation optical equipment, and particularly relates to a method for assembling and adjusting a cassette light pipe. Background technique [0002] A typical cassette light pipe consists of a primary mirror, a secondary mirror, and an image source. The image source is reflected by the secondary mirror and the primary mirror to form an image at infinity. The common method for assembling and adjusting the cassette light pipe is as follows: taking the primary mirror as the benchmark, and adjusting the pose of the secondary mirror and the image source at the same time, so that the wavefront of the system meets the design requirements. This method needs to adjust multiple degrees of freedom at the same time, the operation is complicated, the adjustment period is long, and it is difficult to take into account the adjustment efficiency and the system wavefront quality. SUMMARY OF THE INVENTION [0003] In view...
