Description

Technical Field

[0001] The utility model relates to the technical field of optical instruments, in particular to an interferometer structure. Background Art

[0002] Interferometer is an optical instrument that uses the interference principle to measure the difference in optical path and thus determine related physical quantities. Any change in the optical path difference between two coherent light beams will very sensitively cause the movement of interference fringes, and the change in the optical path of a coherent light beam is caused by the change in the geometric path it passes through or the refractive index of the medium. Therefore, the movement change of the interference fringes can measure the slight change in geometric length or refractive index, thereby measuring other related physical quantities.

[0003] In the prior art, the application number is CN202122980179.X, and the application name is an interferometer structure. The technical solution recorded includes: a fixed plate; a swing arm, the swing arm is pivoted to one end of the fixed plate, and light source devices are provided at both ends of the swing arm; a driving element, the driving element is connected to the swing arm, and the driving element is used to drive the swing arm to swing on the fixed plate. This interferometer structure is provided with light source devices at both ends of the swing arm, and the swing arm is driven by the driving element to swing on the fixed plate, so that vibrating light beams can be generated at both ends of the swing arm. Since the interferometer structure of this technical solution only requires one driving element to generate two vibrating light beams, the interferometer structure is simpler, the equipment operation stability is higher, and the production cost is lower.

[0004] However, there are still some shortcomings in the actual use process. For example, it is not convenient for remote control adjustment during use, and the degree of automation is low, which affects the measurement efficiency. For this reason, we propose an interferometer structure. Utility Model Content
