Abstract
In order to obtain the non-overlapping and high-quality reconstructed image, this paper analyzes the system parameters in digital holographic microscopy. Nowadays a few scholars have analyzed the system parameters which need to satisfy the sampling theorem and spectrum separation conditions. In this paper, not only the sampling theorem and spectrum separation but also the size relationship between the reconstructed plane and the magnified image are studied. Then relationships of system parameters are proposed. First, the maximum object size is directly proportional to the wavelength and microscope objective focal length, inversely proportional to the sampling interval. Second, the minimum magnification is described accurately. Finally, the paper gives the range of recoding distance. Experiments further demonstrate the proposed conclusion’s validity.
