AI Technical Summary

Technical Problem

The prior art has shortcomings in the high-precision spatial positioning and rapid adjustment of optical components, resulting in a long time to adjust the measurement optical path, low accuracy, and inability to effectively control the accuracy.

Method used

A multi-degree-of-freedom beam alignment adjustment system is designed, including a light source, an alignment module and an adjustment module. The alignment module determines the alignment position of the light beam through the rectangular frame structure and the circular hole. The adjustment module realizes the 360-degree rotation, pitch and swing angle adjustment of the optical element through the clamping assembly, the rotary table mechanism, the upper and lower layer adjustment mechanism.

Benefits of technology

It realizes rapid and precise installation, adjustment and positioning of optical components, improves the overall accuracy and stability of the measurement optical path, and solves the problems of long adjustment time and low accuracy in traditional methods.

Abstract

The invention provides a multi-degree-of-freedom light beam alignment adjustment system and method.The multi-degree-of-freedom light beam alignment adjustment system comprises a light source, an alignment module and an adjustment module, the alignment module is of a rectangular frame structure, a left side plate of the alignment module is arranged right opposite to the light source, and round holes are formed in the left side plate and a right side plate of the alignment module; the adjusting module comprises a clamping assembly used for clamping the optical element, a rotary table mechanism used for driving the optical element to rotate, an upper-layer adjusting mechanism used for adjusting the pitching angle of the optical element and a lower-layer adjusting mechanism used for adjusting the swing angle of the optical element, and the clamping assembly is installed on the rotary table mechanism. The rotary table mechanism is installed on the upper-layer adjusting mechanism, and the upper-layer adjusting mechanism is installed on the lower-layer adjusting mechanism. Whether the light beams are aligned or not is detected through the alignment module, the posture of the optical element is adjusted through the adjustment module, and accurate adjustment and positioning of the measurement light path are achieved through combination of the alignment module and the adjustment module.
