Patents by Inventor Raymond Gordon Fielding

Raymond Gordon Fielding has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Projection device comprising a prism system including at least one totally internally reflecting surface at a boundary between two members of different refractive indices within the prism system
    Patent number: 6663243
    Abstract: A projection device includes one or more deformable mirror arrays (803) arranged to spatially modulate incident light. A totally internally reflecting surface (809) is arranged to direct light to and from the deformable mirror array (803). The device may include one or more dichroic layers (805) arranged such that the light incident on each dichroic layer (805) is substantially normal incidence to the layer.
    Type: Grant

  • Projection device
    Patent number: 6250763
    Abstract: A projection device which includes a plurality of deflectable mirror arrays arranged to spatially modulate incident light. A totally internal reflecting surface is arranged to direct light to and from the deformable mirror array. The device includes on or more dichroic layers arranged at an angle relative to the incident light dependent on the spread of angles on the incident beam relative to the optical axis. Additionally or alternatively, the totally internally reflecting surface may be arranged to direct non-spatially modulated light towards a beam dump.

  • Projection system
    Patent number: 5865520
    Abstract: A projection system includes a light source (16) and a prism assembly (41) including at least one air gap (45) effective both to deflect incident light on to at least one reflective spatial light modulator (10), and to transmit modulated light produced by the spatial light modulator (10).

  • Spatial light modulator system
    Patent number: 5704701
    Abstract: A display apparatus for use in a projection system includes a light source, a beam splitter for splitting light from the source into different color component beams and a deformable mirror device spatial light modulators for each different color beam. The light paths to the beam splitter and modulators are provided within a single prism assembly on which the modulators are mounted.
