Abstract
A method of a digital holography based on the use of a self-imaging of the phase element is presented and assessed in terms of image quality and resolution. The experimental results of digital hologram acquisition and reconstructions are given for a standard USAF test pattern. The self imaging effect is used in the reference beam of the Mach-Zehnder interferometer in order to project a structured phase modulated beam directly onto the photosensitive matrix of a digital camera. The main advantage of this method is a simple optical setup and the possibility of performing phase-shifting with a single camera exposure. The numerical reconstruction takes advantage of the Talbot effect and does not involve any approximation or interpolation techniques. In order to evaluate the applicative potential of the method, in this work the image quality is checked for various parameters of the optical setup, especially the period of the self-imaging structure and imaging distances.
