Abstract

The invention relates to an optical grating agglutination alignment mechanism in a space heterodyne interferometer, which is arranged on a base plate of the interferometer, comprises a beamsplitter, optical wedge distance pieces arranged in two paths, an expanding view field prism and an optical grating distance piece, takes on an 'L' shape and is an integrated interference body preposed unit provided with two arm ends which are an X arm and a Y arm. The mechanism is characterized in that a two dimension adjusting mechanism and an angular adjustment mechanism are respectively arranged at the two arm ends of the integrated interference body preposed unit on the base plate; meanwhile, a monitoring system formed by an even light source, an imaging lens positioned on an output optical axis, aCCD photoelectric receiving device and a display; and interference image is generated by the emergent ray of the even light source through the interferometer, and the monitor image can be acquired inthe display. The mechanism is convenient for operation and strong in reliability, and can be used for monitoring the interference effect in real time.

Description

technical field

[0001] The invention relates to an assembly and adjustment mechanism for grating gluing in a space heterodyne interferometer, in particular to a device capable of adjusting the relative inclination angle of the grating lines on two arms and a method for real-time detection of the image effect of assembly and adjustment. Background technique

[0002] Spatial heterodyne interferometer can obtain extremely high spectral resolution in a short spectral range. The system has four parts: pre-collimation system, interferometer system, imaging system and detector system; pre-collimation and imaging The installation and positioning of the lens barrel of the system are very mature. Therefore, the difficulty of the system lies in the accurate positioning of the separate optical elements of the main body of the interferometer, which is the core component.

[0003] The existing desktop optical system is built on a shock-resistant optical platform, and optical components su...
