Problems solved by technology

The phase shifter is supported by a single point, which often causes deviations in the position of the phase shifter, and the recovery performance of the reset decreases over time, and the service life of the phase shifter is short
The price of the phase shifter for multi-point support is often very high, which is not conducive to popularization and use

Embodiment Construction

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments.

[0015] like figure 1 As shown, the rail structure phase shifter includes a base 8 , a main body 10 and an adapter plate 1 . The base 8 is provided with a working groove, and the main body 10 is installed in the working groove. An adapter plate is connected to the upper end of the main body.

[0016] There are two ways to realize the working groove. The first is to use the same material as the base to make an outer frame by rigid connection, and a working groove is formed inside the outer frame. The second is to directly use processing equipment to make a groove on the base. After the groove is ground, it is the working groove.

Abstract

The invention discloses a phase shifter with a guide rail structure. The phase shifter comprises a base, a main body and an adapter plate, wherein a working groove is formed in the base, and the mainbody is mounted in the working groove; an elastic reset structure is connected between the main body and the base; a round hole is formed in the lower end face of the main body, an actuator is installed in the working groove in the base, and the actuator is installed in the round hole; a guide rail mechanism is mounted on the inner wall of the working groove in the base, and is fixedly connected with the main body; a through hole is formed in the side surface of the base, the actuator is electrically connected with a wire harness, a wire buckle is arranged at the end part of the wire harness,and the wire buckle is fixed in the through hole; and the upper end of the main body is connected with an adapter plate. According to the invention, the constraint of main body movement is increased,position deviation is avoided, the service life is greatly prolonged, enterprises are indirectly helped to reduce loss, and the working efficiency of an interferometer is improved.

Description

technical field [0001] The invention relates to the field of interferometer components, in particular to a phase shifter with a guide rail structure. Background technique [0002] At present, in the field of interferometer detection, the use of computer algorithms to calculate the pros and cons of the tested sample reflected by the interferometer fringes is more and more widely used. In the interferometric phase-shifting algorithm, there is a sub-micron level between the sample to be tested and the standard lens, and the displacement curve of each point on the end face of the object being moved is consistent, stable and recoverable. [0003] When the interferometer is calculated by software, it cannot obtain a stable, precise and recoverable displacement, which often brings a large displacement error, resulting in a big difference between the final calculation result and the actual value, which ultimately affects the company's optimization of the sample to be tested. poor j...
