Description

Technical Field

[0001] This utility model relates to the field of laser interferometer technology, specifically to a laser interferometer that is easy to level. Background Technology

[0002] Laser interferometers, as one of the core technologies in the field of precision measurement, play an important role in many fields due to their ultra-high measurement accuracy and non-contact characteristics.

[0003] The structure of an easy-to-level laser interferometer mainly includes a laser source, a beam splitting system, an interference fringe forming area, a detection and calculation system, and an environmental compensation device. Based on the Michelson interference principle, it uses a stable laser as a source and splits the laser beam into two paths through a precision optical system. After reflection, the laser beams are recombined to form interference fringes. In terms of operation, the instrument must first be stably installed on a stable worktable and the optical path adjusted.

[0004] However, in actual use, most of the instruments mentioned above are quite cumbersome to adjust. Therefore, we propose a laser interferometer that is easy to level. Utility Model Content
