Abstract

Background: The installation of optical devices is a necessary operation before their use. Therefore, the configuration of the optical system affects the performance of the whole optical system. However, in the process of optical system installation, there are still some technical breakthroughs to be made in order to better carry out optical system installation in the future.

Objectives: Through the introduction and discussion of the devices, methods and patent features of optical alignment testing in recent years, some valuable conclusions are summarized, and future research and development are prospected.

Methods: The patents of optical system assembly were studied, and the patents and research progress of optical alignment were summarized.

Results: With the development of optical technology, optical alignment has become more and more important, so optical alignment is needed to realize the design of optical systems.

Conclusion: It is concluded that there is still a large space for the development of optical alignment, and the main development trend is towards high precision and large caliber.

Keywords: Optical alignment, optical system, detection, patents, precision, calibration.
