Abstract

The invention relates to the technical field of installation and adjustment of infrared optical systems, specifically to a method for installing and adjusting a refraction and reflection type infrared imaging optical system, and solves the problem of optical elements in a unit cannot be quantitatively detected in an existing infrared optical system installation and adjustment process. The specific installation and adjustment method includes the steps of 1. installing and adjusting all reflectors through laser interferometer, thereby ensuring reflector wavefront quality; 2. adopting a laser tracker to place spatial positions of all transmitting mirrors or a transmitting mirror group; 3. finely adjusting radial positions of transmitting mirrors through interference fringes reflected by the surfaces of the transmitting mirrors, thereby eliminating a residual position error; and 4. Designing the inclination angle between the transmitting mirrors or transmitting mirror group and an optical axis through infrared detector imaging combined with an optical system theory, thereby eliminating residual optical aberration. Through the method provided by the invention, installation and adjustment of the refraction and reflection type infrared imaging optical system can be rapidly, effectively and accurately realized.

Description

technical field [0001] The invention relates to the technical field of infrared optical system installation and adjustment, in particular to an installation and adjustment method based on a catadioptric infrared imaging optical system, which is suitable for the precise installation and adjustment process of a catadioptric optical system for imaging in various infrared bands. This method can Quickly, effectively and accurately realize the installation and adjustment of the catadioptric infrared imaging optical system. Background technique [0002] Compared with other infrared optical systems, the technical indicators of the infrared imaging optical system are more stringent, and the adjustment process is an important stage to ensure the imaging quality of the infrared optical system. With the increase of the optical aperture and the limitation of the cold aperture at the end of the infrared detector, the optical system is basically a catadioptric structure, and generally cons...
