| The laser system of measuring velocity selects appropriate semiconductor laser devices as Light source and a avalanche photon diode as receiver,Research to manufacture can load in particular object, Can realize the accurate distance measurese. According to the relationship of self-triggering signals and range-findingpulses,reverse single-self-triggering pulsedlaser range-finding techniques. High-speed Complex Programmable Logic Device ( CPLD ) chip is used for processing data, The range-finding errors of 10mm are obtained in the range of 30m ,using the SSTPLR techniques respectively. |
