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.
Claims28
A method of presenting a holographic display of a remote work site comprising;
- creating a database of three dimensional surface points of said remote work site;
- dividing said database into a plurality of two dimensional depth planes;
- exposing a near-real-time holographic recording material with each of said two dimensional depth planes;
- developing said holographic recording material to produce a full-parallax three-dimensional image of said remote work site;
- viewing said full-parallax three-dimensional image;
- whereby a near-real-time hologram image simulating natural vision is provided for remote manipulation of an object.
A system for presenting a holographic display of a remote work site in near-real-time comprising;
- database creating means for creating a three dimensional database of a remote worksite;
- dividing means dividing said database in a plurality of two dimensional depth planes;
- holographic recording means;
- exposing means for exposing said holographic recording means to said plurality of two dimensional depth planes;
- developing means for developing said holographic recording means to produce a holographic image of said remote work site;
- viewing means for viewing said holographic image;
- whereby a near-real-time holographic image of said remote work site may be viewed for remote manipulation of an object.
