| Popis: | — A high-pixel-rate, high-contrast (30,000:1) wide-color-gamut grating-light-valve laser projector is reported. A new optical engine enabling high-frame-rate (240 Hz) scan projection is employed. Panoramic wide-angle-scan projection with a 64:9 aspect ratio was also developed. Speckle noise is eliminated using a simple but highly efficient technique. The optical throughput efficiency of the grating-light-valve laser projector is reviewed. |
