A theoretical model to actualize digital holographic detection with the help of paraxial optical system based on the inverse calculation of diffraction is introduced briefly. In addition, we proposed a method to actualize the measurement when the measured object modulates the amplitude and the phase of object light simultaneously. The simulated experimental example will be illustrated with the help of numerical computation and computer-aided image processing techniques.
