Adaptive color conversion algorithm to achieve both high brightness and wide color gamut
We present a new color conversion algorithm for the new projector with the forth liquid crystal panel which controls the yellow light separately from RGB lights of the three-LCD system. This algorithm controls the volume of yellow light and corrects distorted color based on image analysis, and thus achieves high brightness and wide color gamut.
72.2: Invited Paper: Color Processing for Wide Gamut and Multi‐Primary Displays
Until recently most displays were based on CRT. Since all CRTs have similar color characteristics, RGB data represent colors tuned according to the CRT properties, and thus no processing is required at the display end. The emergence of wide gamut displays changed this situation, since rendering of RGB data on wide gamut displays without suitable processing would result in unnatural colors. In the article we discuss color processing for wide gamut displays, and describe algorithms and methods for gamut mapping and multi‐primary conversion.
Coherent pulsed injection seeding of two gain-switched semiconductor lasers
High-power, narrow-spectrum, short pulses at a wavelength near 830 nm are needed for optical logic applications. The authors report the generation of two coherent trains of pulses by pulsed injection seeding of two gain-switched semiconductor lasers with one mode-locked master oscillator. The available power was doubled and both lasers emit in nearly identical spectral lines. Short pulses (30-50 ps) are generated at a repetition rate of 1.9 GHz. The spectrum is reduced to a single mode cluster and shows a 1.7 AA wide chirp suitable for pulse compression. The peak power is 0.1 W for each pulse train. The capability of this technique for coherent power combining is demonstrated.<<ETX>>
