Abstract
A phase shifting digital holography with pre-magnification is designed. In order to fully utilize the bandwidth of the camera, a four-step phase-shifting digital holography is adopted to retrieve the complex distribution of the object. To further enhance the resolution of the reconstructed image without phase aberration, two microscope objectives (MOs) are placed in front of the object and the reference mirror. The MO in the reference arm provides parallel beam at the PZT plane thus improve the precision of the phase shifting. A 1951 USAF negative resolution target is used as the sample. Experiment result demonstrates the feasibility of the proposed method.
