| Abstract: | 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,and the nonlinear error is less than 0.1 %. |
