Multi-sided rotating mirror scanning module solution

1. Basic situation of laser scanning module market With the development of science and technology, applications in the field of optics have gradually become widespread, especially in scientific research and the military. As the scanning component in the optical path, the polygon mirror rotation module is an indispensable part of dynamic measurement equipment such as unmanned driving, laser, robot, and radar scanning. In modern high-precision instruments, the accuracy of optical components is getting higher and higher. The component requirements are also higher. Based on the current high-density...

2. Market demand and pain points At present, the multi-mirror mirror rotation modules on the market mostly use mechanical variable speed transmission to output torque. 1> This solution adds additional transmission components, The gap between the machines will increase the output error, also increase the failure rate and cost, which not conducive to digital control. The output speed directly affects the overall life; 2> Usually to extend the service life The output speed is not too high, which limits the scanning frequency and cannot meet the requirements of high-speed scanning.

3, market demand and pain points, Power Motor solutions and provided results To solve the problem of multi-face rotating mirror modules on the market, Power Motor adopts MCU+brushless motor+optical encoder design. The brushless motor directly outputs torque to the mirror module, and the high-performance MCU processes floating-point data. Realize high-precision data calculation, with optical encoder and special algorithm processing, the accuracy error of the whole calculation system is controlled within ±0.00001%, coupled with the brushless motor can finally achieve ±0.00005% speed stability output,...

4. Future prototype planning and optimization in this field In the existing control accuracy, design a smaller volume and quality, higher scanning frequency (that is high output speed>=20000RPM), and more convenient for mass production of high-speed multi-face rotating mirror module.
