Definitions

  • Figure 2 is a cross-sectional top view of a dichroic prism assembly. Detailed Description - . the
  • a first thin-film-transistor/liquid crystal light valve (TFT-LCLV) 22a is mounted on a prism assembly back face 24, opposite to an outlet or projection face 26 of prism assembly 10; other TFT-LCLVs 22b and 22c are each respectively mounted on opposite side faces 28 and 30 of prism assembly 10.
  • a green light source 32 is mounted in alignment with TFT-LCLV 22a; a red light source 34 or a blue light source 36 is respectively mounted in alignment with an associated one of TFT-LCLV 22b or 22c.
  • a single set of reflector optics is used to form an independent image for each eye, thus offering a very simple system without any obscuring structure in front of the wearer's eyes.
  • spherical reflector 54 is substantially dome-shaped, the reflected images will cross when reflected by spherical reflector 54 and plane reflector 56, as shown in Figure IB.
  • the image produced by the dichroic prism assembly on the left side of the helmet will be projected into the wearer's right eye and the right side dichroic prism assembly image will be projected into the left eye.
