[0002] In the process of integrated testing and photoelectric detection of optomechanical parts and assemblies, it is often necessary to use color difference sensors, inductive probes, lever micrometers and other measuring instruments to detect the end jump and radial jump of optomechanical components. However, with the emergence of optomechanical parts of different heights and the increase in the height of optomechanical assemblies after the accumulation of integration work, the measuring instruments will not be able to meet the measurement conditions after exceeding a certain height.
