Abstract
A near-real-time holographic display for operations at a remote work site where a three dimensional database is collected with a laser range scanner. The database is then divided into discrete two dimensional segments or depth planes. A holographic recording material is then sequentially exposed to multiple depth planes through a stack of three spatial light modulators in a multiplane exposure process. This procedure is repeated for all depth planes in the database. The holographic recording material is then rapidly developed for viewing of the remote work site in a holographic image that simulates natural vision.
