China Received May 04 2016 Revised September 09 2016 Accepted October 10 2016 Abstract Background Objective The design and optimization of laser detection system based on MEMS Micro-electro Mechanical Systems scanning mirror is presented in the paper. According to requirements of application it adopts the laser module to design the laser driver circuit and the designed modulation circuit can satisfy the actual needs. Method The designed information processing module is composed of the echo receiving module signal amplification and filter circuit module and the synchronous circuit of measuring angle and distance etc. Conclusion It gives out the distance decoding method and explores the method of capturing echo signal which can fast and accurately calculate the distance and azimuth information of scanning. Keywords MEMS Micro Scanning Mirror Integration Space target Detection Design. 1. INTRODUCTION In the scanning methods of the optical system the traditional mechanical scanning system is the most widely adopted method which includes mirror prism scanning etc. It has the advantages of simple structure and large scanning angle etc. but its limitation is that it has large inertia of mechanical movement low scanning speed heavy weight etc. The acoustic optic electro-optic or binary optical scanning are emerging technologies in recent years and their scanning speeds are very fast but the .
