Laser measuring system

Abstract

The invention discloses a laser collimation-measuring system. The laser collimation-measuring system includes a first laser source (1) and further includes a second laser source (2) and a light combining device (3), wherein the first laser source (1) and the second laser source (2) respectively emit first laser (8) and second laser (9) to the light combining device (3); third laser (10) and fourth laser (11) are respectively generated after the first laser (8) and the second laser (9) pass through the light combining device (3); and the third laser (10) partially overlaps the fourth laser (11). In the prior art, single laser source emits laser to measure collimation, which brings the problem that since the laser emitted from the single laser source is elliptic, an error may occur often due to non-uniformity of two sides of the laser during collimation measurement; in addition, the laser emitted from the single laser source has low intensity and is prone to interference. By the above technical solution, the light intensity of the laser may be enhanced, thereby making the two sides of the laser uniform and reducing collimation-measuring error on the premise of ensuring that the laser is not prone to interference.
