Description

TECHNICAL FIELD

[0002] Optical systems have a wide range of applications in daily life. The alignment of optical systems is the last step before the optical systems are put into use, which directly determines the accuracy and stability of the system. It can be said that qualified alignment is the premise of stable operation of the optical system. Unlike common related light paths, double-layer non-related light paths have two independent optical systems, and there is no direct reference transmission between the two optical systems. This results in the need to align the two independent optical systems separately when aligning the double-layer non-related light path. When aligning the lower optical system, the entire system needs to be flipped, which causes the problem of secondary clamping of the system, cannot guarantee the coaxiality of the upper and lower light paths, and the optical elements are easily knocked during the manual flipping process, which is risky. This operation method needs to use a theodolite to transfer the reference during the flipping process, which is complex and extremely inconvenient to operate. SUMMARY

A method for calibrating a flip device for calibrating a double-layer uncorrelated optical path according to claim 8, characterized in that, During the process of controlling the lifting rods of the first lifting cylinder (2), the second lifting cylinder (4), the fourth lifting cylinder (8) and the fifth lifting cylinder (9) to rise or fall, the lifting height feedback from the four encoders is collected in real time, and the lifting height of the first lifting cylinder (2), the second lifting cylinder (4), the fourth lifting cylinder (8) and the fifth lifting cylinder (9) are adjusted and controlled in real time according to the lifting height to ensure that the lifting height is consistent in real time.

10. A method for calibrating a flipping device for calibrating a double-layer uncorrelated optical path according to claim 8, characterized in that, The specified height refers to the height that ensures the double-layer unrelated optical path is not blocked by the base plate (3) during the flipping process.
