Abstract
An automatic angular-spectrum filtering for the phase reconstruction of dual-wavelength digital holograms in a common-path configuration is presented. The major procedure of this automatic angular-spectrum filtering consists of excluding the zero-order region of Fourier spectrums and locating the center of order +1 region of the angular spectrums for two individual wavelengths. The phase map of the object is retrieved with the automatic angular spectrum-filtering algorithm in dual-wavelength digital holographic system, which demonstrates that the automatic angular spectrum-filtering algorithm is feasible and effective. It provides an efficient solution for angular-spectrum filtering in real time dual wavelength digital holographic microscopy.
