Optical scanning holographic system for the recognition of 3D objects

We describe a novel holographic technique for the recognition of 3D objects. We first briefly review an optical heterodyne scanning technique. We will then discuss the use of the technique to create a hologram of the 3D reference object and show how to use this holographic information for 3D object recognition. Finally, we address the important and practical z-invariance of the system and show that the overall scheme of the system is 3D shift- invariant. Computer simulation will be provided for the classification and confirmation of the idea.
