Description

Technical Field

[0001] The invention relates to the technical field of optical debugging devices, in particular to a simple six-dimensional optical debugging device. Background Art

[0002] A collimator is an optical light path that separates and decomposes light pulses. It uses optimized refractive and reflective optics to not only achieve fast light conversion but also decompose a compact input light pulse into multiple pulses in a limited space.

[0003] This technology uses refraction and reflection to process optics, and then a closed lens system cuts the light pulse into multiple pulses and directs them to different imaging systems, ultimately achieving rapid decomposition of the laser. The accuracy of the mechanical structure often does not reach the optical accuracy, so a mechanical structure that can achieve six-dimensional adjustment is required to cooperate with optical elements to improve the accuracy of the optical system, and the structure must be stable enough for daily use. Collimator tubes are difficult to mass-produce, and most of them are in the form of gaskets, which greatly affects the production volume of collimator tubes. Therefore, an improved technology is urgently needed to solve this problem existing in the prior art. Summary of the invention

[0004] The purpose of the present invention is to provide a secondary mirror mechanism and a primary mirror mechanism that can perform independent movements of translation, rotation, tilt, pitch, power, and up and down, thereby improving the debugging accuracy of the collimator and greatly reducing the research and development time and cost of the collimator. The small-aperture collimator can be carried and used outdoors, is suitable for coaxial collimators, and can be used for multi-reflection systems, greatly improving the accuracy of the parallel light beam generated by the collimator for detection and calibration of the optical system, and providing a simple six-dimensional optical debugging device to solve the problems raised in the above-mentioned background technology.
