Paper Abstract

A 2D image can be scaled simply by changing its pixel size. If we were to apply this method to a hologram, it would cause distortion in the reconstructed 3D images, and a change in the viewing angle. We propose a method for scaling the reconstructed image without changing its fringe element, i.e., pixel size. We divide the hologram into small blocks. Then, these blocks are repositioned in order to magnify or demagnify the reconstructed image. This method maintains the viewing angle and causes no distortion. It does, however, blur the reconstructed image. To reduce the blur, we propose a method of interpolation in the frequency domain. Results of experiments performed on an electro-holography system are also presented.
