Structure for freely adjusting direction of optical axis of laser

Abstract

The invention relates to the technical field of engineering measurement and more particularly to a structure for freely adjusting the direction of the optical axis of a laser. The adjusting mechanism comprises a base, a flexible hinge structure, an upper cover, and a plurality of adjusting screws. The flexible hinge structure is fixed inside the base; the upper end of the base is fixed to the upper cover; the laser is fixed in a circular hole in the center of the flexible hinge; the adjusting screws pass through the upper cover to be abutted against the upper part of the flexible hinge structure. The laser is a semiconductor laser with a diameter of 20mm and a wavelength of 650nm. The base material is 6061-T6 aluminum alloy. The flexible hinge is made of spring steel material and quenched, and has good flexibility. The semiconductor laser is fixed to the flexible adjustment mechanism by being locked in the radial direction by locking screws, and the precision adjustment of the laser optical axis can be realized by adjusting the four adjusting screws arranged orthogonally on the upper end face of the base in the hinge direction.

[0003] At present, there is no fixed angle relationship between the shell and the optical axis of commonly used lasers. After installing the laser according to the size of the shell, it is necessary to make precise pointing adjustments to the outgoing optical axis of the laser. At present, the common method is to use the repair and research installation base The precise pointing of the optical axis can be achieved by using the surface method, but the installation and adjustment of this method is time-consuming and laborious, and it is difficult to realize the occasions requiring fast installation.

In addition, a two-dimensional orthogonal rotation mechanism is designed to realize the adjustment of the optical axis pointing. This method has the disadvantages of complex mechanism and large volume.
