Based on the analysis of the fundamental principle of the recording and reconstruction of white-light fresnel incoherent digital holography, the relationship between the reconstructed image resolution and recording parameters is discussed in detail. With two different types of phases loaded on the spatial light modulator (SLM), numerical simulation and experimental research of white-light fresnel incoherent digital holography are implemented respectively to analyse the relationship between image quality and recording parameters quantitatively. Results show that white-light fresnel incoherent digital holography based on SLM can realize the recording and reconstruction of three-dimensional object rapidly in a single channel and motionless way. Theoretically, a high quality reconstructed image with the same maximum resolution can be obtained, whichever phase loaded on SLM it is, a plane wave and a spherical wave or two spherical waves. However, due to the different requirements of the bandwidth of the light source and CCD size in the experimental study, the recording condition of loaded phase of two spherical waves is greatly reduced than that of loaded phase of a plane wave and a spherical wave. Under the same experimental conditions, the former reconstructed image resolution is much higher than the latter.
