Problems solved by technology

[0004] The purpose of the present invention is to propose a method for detecting the optical efficiency of the reflective surface of the primary mirror of a large-diameter photoelectric telescope, to solve the problem that the efficiency of the reflective surface of the primary mirror of a large-diameter photoelectric telescope cannot be detected online in the prior art, and to determine the optical efficiency of the reflective surface of the primary mirror. Whether the efficiency can meet the requirements of use and whether it needs to be cleaned, so as to avoid frequent cleaning of the reflecting surface of the primary mirror

Abstract

A method for detecting the optical efficiency of the reflective surface of the main mirror of a large-diameter photoelectric telescope belongs to the technical field of photoelectric instruments. question. In the present invention, a set of monitoring and testing lens components that can be quickly disassembled and detected is installed on the inner wall of the main mirror through a fixing device. The monitoring and testing lens components include a picture frame and a test lens; The reflective surface is in the same use environment; the material of the test lens is the same as that of the main mirror, and the film is coated at the same time, and the coating layer on the surface of the test lens is the same as the film structure of the reflective surface of the main mirror. The optical efficiency of the mirror surface of the primary mirror. The invention replaces the detection of the optical efficiency of the reflection surface of the main mirror by detecting the optical efficiency of the test lens, which is simple, convenient and low in cost.

Description

technical field [0001] The invention belongs to the technical field of photoelectric instruments, and in particular relates to a method for detecting the optical efficiency of a main mirror reflection surface of a large-aperture photoelectric telescope. Background technique [0002] Large-aperture photoelectric telescopes are mainly used for real-time measurement of the position and trajectory of flying targets in the air. Generally, the optical system of a large-aperture photoelectric telescope is open and exposed to the working environment when it is working. Even when working in the field with a relatively harsh environment, it is difficult for the entire optical system of the large-aperture photoelectric telescope to be in a sealed state. Therefore, the surface of the corresponding lens will be There are dust and other attachments, especially the pollution of the primary and secondary mirrors that are directly in contact with the external environment in the optical syste...
