Abstract

Starting with the numerical calculation of the Fourier spectrum of the orthogonal phase-coded beam, a fundamental study on hybrid phase-coding and spatial multiplexing shows that there will be a complex and serious fluctuation in both intensity and phase distribution in the reference beam if a Fourier transform configuration is used for setting up the reference beam. In order to maintain phase-only modulation and orthogonality in the reference beam pattern, we suggest that the phase modulator should be imaged to the recording plane.
