Abstract
A method of using a display system having a spatial light modulator (14) to display holographic images. The spatial light modulator (14) generates images that represent vertical strips of a hologram. These images are de-magnified by a three-dimensional optics unit (18), in the horizontal direction so as to form image strips. A scanning mirror (45) scans the image strips in a series across an image plane at a rate sufficiently fast that the viewer perceives a composite hologram comprised of these image strips.
Claims17
A method of using a spatial light modulator to generate holographic images, comprising the steps of:
- accessing holographic data;
- generating an image on said spatial light modulator that represents a vertical image strip of a fringe pattern of a hologram represented by said holographic data;
- de-magnifying said image in the horizontal direction so as to decrease the horizontal size of said image strip;
- displaying said image strip on an image plane at a first position on said image plane;
- repeating said generating, de-magnifying, and displaying steps for a number of image strips, wherein said displaying step is performed by displaying said image strips in a horizontal series across said image plane, and wherein said repeating step is performed at a rate such that a viewer may perceive a complete image on said image plane.
A display system for displaying holographic images, comprising:
- means for accessing holographic data;
- a spatial light modulator for generating images that represent vertical image strips of a hologram represented by said holographic data;
- at least one de-magnifying lens for de-magnifying said image strips in the horizontal direction;
- and
- a scanning mirror for directing said image strips to adjacent positions on an image plane such that said scanning mirror scans images produced by said spatial light modulator to allow perception of a complete image comprised of said image strips.
