Method for assembling and adjusting full-free-form surface multi-reflection off-axis optical system

The invention relates to an installation and adjustment method of an optical system, in particular to an installation and adjustment method of a full-free-form surface multi-reflection off-axis optical system, which is used for solving the problems that the installation and adjustment freedom degree of the full-free-form surface multi-reflection off-axis optical system is large, the relation between optical axes of all optical elements is complex, the system integration difficulty is increased, and the installation and adjustment precision is high. And the installation and adjustment process is not easy to monitor. According to the assembling and adjusting method of the full-free-form surface multi-reflection off-axis optical system, a space coordinate system is established through space coordinate measuring equipment, all reflectors are accurately positioned in combination with an auto-collimation theodolite and a cubic mirror, a microscope and a measuring target ball are used for reference transmission and
