Abstract:
A laser range-finding system based on field proprammable gate array(FPGA) is investigated.By coding and decoding laser signals,scaling down the clock of launching part of the laser system and using the phase-locked loop in the FPGA to mutiply the frequency,the aim of laser ranging is completed.These make the system more stable and accurate.In the receiving part of the system,the backward wave of laser using the window function is received in an active way instead of a passive way.Using the spectral filter in this part can increase the noise immunity of the system.The test results show that the laser range-finding system obtains the expected effect.
