Formation and inversion of pseudoscopic images.
The reconstruction from an integral photograph is pseudoscopic. It is usually inverted into an orthoscopic image by a second recording and reconstruction process. Some schemes are described which perform this inversion without the need for a second recording. All schemes use some form of autocollimating screen, i.e., a screen which reflects a ray of light back onto itself. The inversion can either be formed on the scene (inversion from orthoscopic to pseudoscopic) before the integral photograph is recorded or it can be performed on the pseudoscopic reconstruction. Some theoretical considerations concerning the optimum screen are given. The relation between these schemes and integral photography,image dissection, and a previously proposed scheme are given.
