@@@@The study of the seismic wave detection system based on PSD sensor is introduced in great detail .The system taking a semiconductor laser as light source applies PSD sensor to detect the motion of the ground vibration .The current output of PSD bipolar is conveyed to a computer through the AD converter by a change of current to voltage and amplification . MATLAB simulation shows that the amplitude ,frequency and other information of seismic wave can be accurately detected ,and error is less than 1% .
