摘要：

We present several methods for optoelectronic processing of two- and three-dimensional images based in digital holography. Two-dimensional 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 cedes. As conventional holograms, digital holograms contain information about shape, location and orientation of three-dimensional objects. This allows us to apply three-dimensional pattern recognition techniques with high discrimination. We also measure three-dimensional orientation changes using the information contained in digital holograms. Experimental results are presented.
