Abstract

A video projection system can utilize an advanced xenon short arc lamp to obtain a bright, high-resolution color image using a sufficiently cost-effective, compact and lightweight design. An unwanted radiation component of a white light beam produced by the xenon lamp, such as an infrared and/or ultraviolet component, can be removed using any of a number of approaches, such as using a dichroic coating on the input end of an integrator rod or the exterior circumference of a light tunnel. Alternatively, a beam separating mirror can be used to remove the unwanted component. An advanced color wheel also can be used which has high transmittance over the unwanted spectrum and high reflectance over the visible spectrum, in order to transmit the unwanted radiation out of the beam path of the projection system.
