Active Projection Of LCD-TVs With A Copper Vapor Laser Brightness Amplifier

An active projection system with a copper vapor laser for LCD-TV pictures is constructed. The maximum size of the projected image is 1.6 m in diameter. Illuminance of the image is then 0.5 W/m2. We estimated the image quality: resolving power of the system, fidelity of the gray levels, background noise and speckle.
