Abstract :
We present several optoelectronic techniques based on digital phase-shifting holography for security applications. Information codified as both two-dimensional (2D) images and 3D scenes is optically processed and captured electronically. Subsequent digital processing is then also performed. Applications include 2D and 3D encryption, 3D perspective reconstruction, 3D pattern recognition, and 3D orientation measurement
