Abstract

Holograms are created by recording the interference pattern obtained between the object called object wave and a coherent reference wave. Computer-Generated Holography (CGH) deals with the creation of holograms with the aid of computers. CGH makes use of the wave theory of light to represent both the object and reference waves. CGH does not require actual objects to create the hologram as long as the light scattered or diffracted off the object could be represented mathematically. The proposed work describes a method for creating holograms with the help of a computer along with the technique to reconstruct its image. Iterative Fourier Transform algorithm is used to optimize computer-generated Fourier holograms. Root mean square error is measured to evaluate the quality of the reconstructed image.
