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, a CCD 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 in the 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 a grating gluing assembly and adjustment mechanism in a spatial heterodyne interferometer, in particular to a device capable of adjusting the relative inclination of the grating lines of two arms and a method for real-time detection of the effect of the adjustment image. Background technique [0002] The spatial heterodyne interferometer can obtain extremely high spectral resolution in a short spectral range. The system is equipped with four parts: front collimation system, interferometer system, imaging system and detector system; front collimation and imaging The lens barrel installation and positioning method of the system is very mature. Therefore, the difficulty of the system lies in accurately positioning the separate optical elements of the main body of the interferometer, the core component. [0003] The existing desktop optical system is built on an anti-seismic optical platform, and optical elements such as gratings, beam sp...
