Design of High-speed Sampling System in Pulse Laser Application ()
Abstract
In measurement system by means of pulse laser, such as
plasma measuring, laser ranging, the amplitude of echoed laser wave is very weak
and difficult to detect by traditional analog electronic
technology. A digital high speed data acquisition and processing system
was designed to meet the accuracy requirement. It adopted high speed AD chip
and advantage FPGA chip as core unit. Experiment results have verified this system can reach to 1GHz sample rate and can catch weak echo wave
effectively and the measuring accuracy is improved markedly.
