Paper Abstract

Optical Scanning Holography (OSH) is a technique that records the three-dimensional information of an object through optical heterodyne scanning. This system has two pupils which enhances processing power and spatial filtering capabilities. Analysis of proposed OSH system in this paper includes two configurations of pupil pairs. In the first case, one pupil is a pulse, and the other is a Gaussian function. The OSH system analyses the adoption of a random phase and Gaussian pupil in the latter case. In the proposed system, the optical transfer function of the recording and reconstruction stages is found out. Subjective evaluation of the optical transfer function is investigated in terms of resolution. Simulations are performed for different parameters of the Gaussian function, various random distributions of the random phase pupil and for other objects. These results can be used with sectioning applications.
