In order to study the influence of wave front reconstruction methods on the reconstruction field quality and the calculation speed during the application of color digital holographic detection and the accurate integration of different wavelengths and reconstruction field, the method of accurate overlap of the reconstruction field of the different color and object light and the detailed process of wavefront reproduction in real time of digital holographic color were given by theoretical analysis and experimental verification. The characteristics and the calculation rate of several wavefront reconstruction algorithms were analyzed and compared. The results show that variable magnification wavefront reconstruction algorithm using spherical wave as reconstruction light can adapt to objects in various size, obtain higher resolution images with less computing time and it is better for color digital holographic detection applications.
