Abstract

A method of recording four quadrature-reference-wave-holograms by CCD and reconstructing the object wave front by numerical calculation is presented in this paper. The terms of direct transmitting, auto-correlation and conjugate wave in the four reconstructing waves are cancelled out and only the original object wave is left after overlapping. Reconstructed images are obtained by calculating through Fresnel-Kirchhoff integral on computers. The influences of the noise of CCD and the phase-shifting error of phase-shift elements to the quality of the reconstructed images are analyzed. Experimental results show that pure original object wave or the conjugate object wave can be reconstructed in in-line holograms using the method in this paper.
