Abstract
The principle of optical scanning holography (OSH) has been recently proposed by Poon et al. to acquire horizontal-parallax-only (HPO) holographic information electronically. Although many ideas of HPO-holography have bcen proposed and studied, to the best of our knowledge, this is the first proposcd electronic holographic technique to acquire HPO-holographic information. In this Chapter, we first briefly review OSH and then discuss how HPO-holographic information can be acquired using OSH. We provide computer simulations to illustrate and clarify the idea. We also propose and discuss a possible optical reconstruction scheme for twin-image elimination using only two holograms as well as a digital scheme for HPO-holographic reconstruction.
