Abstract: A stereoscopic projection system and method of generating light that include two or three infrared lasers, two optical parametric oscillators, and six or seven second harmonic generators. Six colors of visible light are produced. Three bands of red, green, and blue form an image for the left eye of the viewer, while the other three bands of red, green, and blue form an image for the right eye of the viewer.

Abstract: An apparatus and method that reduces laser speckle by using stimulated Raman scattering in an optical fiber. The fiber core diameter and length are selected to achieve a desired output color. An adjustable despeckler is formed by combining two optical fibers in parallel and adjusting the amount of light in each path.

Abstract: A projection screen that reduces speckle by separating reflective flakes by at least 100 micrometers. The reflective flakes are held in a binder material that is coated on a backing layer. In a laser projection system, the separation distance between reflective flakes may be at least twice the coherence length of the laser light.

Abstract: A stereoscopic display system and method of stereoscopic projection that include a polarization-switching light source and a polarization-preserving projector. The polarization state of the polarization-switching light source is synchronized with alternate projection of left-eye images and right-eye images. The polarization-switching light source may include a laser and a rotating disk, and the disk may include a waveplate that switches the polarization state as the disk rotates.
