  • Projection systems with despeckled laser light
    Patent number: 9599835
    Abstract: An apparatus and method for the projection of stereoscopic images that includes a pulsed laser that generates green light and an optical fiber that generates stimulated Raman scattered light. The stimulated Raman scattering light is divided into green light and red light and the colors are used to form stereoscopic images. Additional lasers may be added to meet specific primary color targets and to balance the brightness of the images for each eye.
    Type: Grant
