Abstract:

Fourier transform holography overcomes the phase recovery challenge by recording complex field information of the object in an interference pattern recorded at the far field, i.e., Fourier plane. Moreover, this geometry helps to reconstruct the complex field of the object from a single Fourier transform which is an attractive feature for numerical reconstruction of the digitally recorded hologram. In this paper, we present a nearly common path experimental design for recording of a digital Fourier holographic hologram using a beam displacer, and recover the complex valued objects using the Fourier analysis. The performance of the system is experimentally examined for different objects.

Keywords: Digital Fourier transform holography; phase imaging; common path configuration
