Abstract

In this paper a novel opto-electric phase discriminator array implemented with CCD is presented. It has the potential application in scannerless three-dimensional imaging system. As it works, a sinusoidal light signal is detected by a CCD receiver. CCD's exposure is controlled with square wave that has the same frequency as incident light intensity. Thus the correlative operation is processed in CCD automatically. CCD's output signal contains phase information of input signal. In order to figure out the unique phase shift between the sinusoidal signal and the square wave signal, triple measurement methodology is adopted. In our experiment, the RMS error of measurement is about 0.2%.
