Abstract

The noise has a serious effect on the quality of the three-dimensional holographic images reconstructed. A new method is proposed to improve the Burch code and combine it with the three-step phase shifting method to remove the noise. The reconstructed images are with the high contrast and resolution. The three-dimensional reconstruction images are compared with the ones of median filtering and of 20-time intensity superposition method. The performance parameters of three methods are analyzed. The experimental results show that the zero-order light spot, conjugate image and speckle noise are suppressed effectively. The quality of the reconstructed image is noticeably improved.
