The invention provides a deflection angle measuring and dynamic monitoring device of a beam expanding system, relating to the field of optical beam expanding machinery. The device comprises an emission system, a reference reflector assembly, a monitoring assembly, a first fixing frame and a second fixing frame, wherein one end of the first fixing frame is connected with one end of the second fixing frame in a rotary manner; the reference reflector assembly is installed at the other end of the first fixing frame; the monitoring assembly is installed at the other end of the second fixing frame;and the emission system is arranged outside the reference reflector assembly. The device has the following beneficial effects: the device provides the assembling and adjusting reference in the assembling and adjusting state; and in the working state, the device monitors the angle deflection of the beam expanding system in real time and provides dynamic monitoring of the deflection angle of the laser passing through the beam expanding system for the laser emission system, so that mechanical structures and other structural components of the laser output fluctuation and beam expanding system canprovide feedback and adjustment directions for the impacts of environment variation (such as temperature variation and the like) on the laser emergence angle.
Description
technical field [0001] The invention relates to the technical field of optical instruments, and relates to a deflection angle measurement and dynamic monitoring device for a beam expander system. Background technique [0002] Laser is a kind of light beam emitted by a laser with the advantages of high brightness and high collimation. The beam directly emitted by the laser is usually a narrow and high-energy beam. These excellent characteristics of the laser beam have unique advantages in many aspects. . But precisely because of these characteristics of the laser, the beam directly emitted by the laser usually needs beam expansion and other beam conversion before it can be applied in practical work, such as in laser holography technology, laser far-field lighting technology, optical communication technology, laser measurement technology Wide beams are needed in such fields, and the function of the laser beam expander system is to convert the narrow laser beam directly emitte...
