ONE-STEP ORTHOSCOPIC IMAGE RECONSTRUCTING TECHNIQUE FOR A HOLOGRAM CONSTRUCTED THROUGH A DISPERSIVE MEDIUM

摘要

A technique for reconstructing an orthoscopic image of an object from a hologram that has been constructed of that object through a radiation dispersion medium. The technique includes reconstructing from the hologram a first order diffracted beam with a wave front conjugate to that of the dispersed object bearing wave front recorded on the hologram. The first order diffracted beam is reconstructed in a manner to form in real space an image of the dispersive medium used during the hologram construction. A phase conjugate of the dispersive medium used in the hologram construction is positioned in the reconstructed beam. An orthoscopic image of the object is thereby formed.
