Paper Abstract

We present several methods for optoelectronic processing of 2- and 3-D images based on digital holography. 2D objects are optically encrypted by using on-axis digital holography. The digital hologram is obtained with phase-shifting interferometry. The encryption of the hologram is performed by using random phase codes. As conventional holograms, digital holograms contain information about shape, location and orientation of 3-D objects. This allows us to apply 3-D pattern recognition techniques with high discrimination. We also measure 3-D orientation changes using the information contained in digital holograms. Experimental results are presented.
