Abstract
A three-dimensional display apparatus (10) that can be used to display conventional pseudo three-dimensional images and true three dimensional images using a CRT screen (96), or an array of digital micromirror devices (152) or an array of activated micromirrors (174), or any other devices that can activate/deactivate multiple pixels, simultaneously, at a high speed.
Claims15
A three-dimensional display apparatus comprising:
- a screen;
- a screen moving assembly for moving the screen to a select number of different depth locations along a longitudinal axis defining a screen travel path;
- and
- an imaging assembly for displaying images on the screen as it is moved, the imaging assembly including
- circuitry for receiving a 3D signal representative of a three-dimensional image and for separating the signal into a plurality of 2D signals each representative of a two-dimensional image within the three-dimensional image, and
- a plurality of image generators coupled with the circuitry by a plurality of channels for generating on the screen the two-dimensional images in a concurrent fashion as the screen is moved by the screen moving assembly.
