Abstract
Optical scanning holography (OSH) can perform high quality, speckle-free three-dimensional (3D) holographic imaging. However, conventional OSH system contains an interferometer, which is sensitive to environmental disturbances. Here, we develop an interferenceless OSH (IOSH) system to overcome this issue. In IOSH, the interferometer is replaced by a digital micro device (DMD) together with a projection module. The Fresnel zone plates are directly displayed on the DMD and projected to the object target. The high frame-rate DMD can serve as both the display device and the scanning device, and thus the system can be compact, robust, and low cost. We have studied the system performance by analyzing the 3D complex point spread function. The ability of 3D imaging by IOSH has also been demonstrated experimentally.
