摘要：
A reflective lensless on-axis digital holographic microscopic system with a spherical reference wave was developed and used to obtain a reconstructed image at several magnification levels. A polarization image camera (PIC) was used to suppress the direct current term and twin images of the on-axis digital holography (DH) microscope. The PIC was used in a parallel phase-shifting DH system without mechanical movement. Here, we show that the magnification can be adjusted by changing the ratio of the distance between the object and the PIC to that between the reference light and the PIC while maintaing a constant reconstruction distance.
