Paper Abstract

In this paper, we demonstrate the application of the spiral phase filter for image enhancement in phase shifting digital holographic microscopy system. The method is based on Fourier plane filtering of the microscopic image with a spiral phase filter which is located at a computer controlled Spatial Light Modulator (SLM) in the optical imaging pathway of phase shift digital holographic microscopy system. Spiral phase filter is designed by radial isotropic Hilbert transform. The spiral phase filter as a spatial filter in Fourier plane of an imaging setup has been proposed as an isotropic edge detection method providing strong contrast enhancement of microscopic amplitude and phase objects. Since all threedimensional information is captured by phase shifting digital holographic microscopy, the reconstructed phase object or cell is reconstructed clearly observed in three-dimension.
