PSD detection technique based on phase method has advantages of simple processing circuit
high detecting precision
strong anti-interference ability and good environmental adaptability
compared with amplitude method.A micro-displacement measurement system based on LabVIEW and 2D duo-lateral PSD is designed.Experimental results reveal that the phase difference of the PSD output signal and the light spot position have good linear relation
