Detecting small changes in process images with digital holography

This paper presents a method for detecting the small changes of image, using digital holography. A hologram is constructed from a simple image using composition of spherical waves. After changing the image, a second hologram is constructed. The two holograms are subtracted and resulting hologram is observed. The results show that for small change in the image there is a great alteration in the hologram. The experiment is repeated for process images. A great change of hologram content also occurred after changing the intensity of only one pixel.
