Abstract

The invention discloses a computer-aided installation and adjustment method of a coaxial optical system. The computer-aided installation and adjustment method comprises the following steps of S1, establishing an optical model of an optical system to be installed and adjusted, and separately establishing n optical sub-systems along the optical path direction, wherein the n optical sub-system comprises optical elements 1-n; S2, selecting the image plane positions of each optical sub-system and obtaining an ideal wavefront aberration through simulation analysis; S3, introducing a position deviation amount to the optical element n in the n optical sub-system to obtain a simulated wavefront aberration; S4, solving a sensitivity matrix corresponding to each optical sub-system by adoptinga sensitivity matrix formula; and S5, solving the actual position deviation of the optical element n in the n optical sub-system by utilizing the sensitivity matrix and the actual wavefront aberration, and adjusting the optical element, so as to successively complete the installation and adjustment of the n optical sub-systems. By adoption of the method, the problem of mutual compensation ofpositions of all the optical elements in the adjusting process can be avoided, so that the convergence speed in the assembling and adjusting process is accelerated, and the assembling and adjusting precision and the assembling and adjusting efficiency are improved.

Description

technical field [0001] The invention belongs to the field of optical technology, and more specifically relates to a computer-aided adjustment method for a high-precision coaxial optical system based on the sensitivity matrix method, which can be applied to the precise adjustment of the optical system and the improvement of imaging quality. Background technique [0002] The traditional optical system adjustment mainly relies on the experience of the adjustment personnel and is completed with the help of simple adjustment equipment, which has the disadvantages of large blindness, long adjustment cycle, low precision, etc., and is not suitable for the installation and adjustment of large-aperture or near-diffraction-limited optical systems . With the continuous development of computer technology, optical design and optical detection technology, computer-aided adjustment of optical system becomes possible. With the increasing demand for high-precision optical system application...
