【Abstract】 Long-distance laser ranging is one important subject to be studied, and one important concept of this project is the laser ranging finder’s control system and information system. In this paper, a system with FPGA chip is introduced to meet this need. This system solved the traditional laser ranging finder’s control system apart from the information system. Firstly, It was to introduced the laser ranging find technique development, classification and factors that be influences the measure accuracy, then, analyzes every kind of factor that affect the pulse laser ranging precision, and educed the main factor influence the ranging precision. Combining together the FPGA technique characteristics, putting forward an exaltation measure method this paper adopted. And then, detailed introduce programmable logic Device development, design techniques, point introducing FPGA design steps, method and hardware description Language development. Finally, describe the hardware and software design for the system, capability and index signs of the system.This text design a laser ranging finder’s whole machine control system and information system. This system successful proceeds the outfield experiments, getting the good test the result.更多还原
