Abstract

The intermediate angular-spectrum method is an efficient way to calculate computer-generated holograms without zero-padding and cropping operation. In this paper, we present an optimized iteration algorithm to improve the reconstruction quality in the intermediate angular-spectrum method. The quadratic phase is multiplied with the target image as the initial complex amplitude distribution to suppresses the speckle noise and the freedom domain is introduced in the image plane to improve the reconstruction quality. Numerical simulations and optical experiments are performed to demonstrate that proposed method is an effective method for high-quality reconstruction. It is expected that proposed method could be widely applied in the holographic field in the future.
