Abstract
The present invention provides a light source for a projector system, and method of operating the light source as well as a projector system that provides: i. a substantially uniform brightness across the surface of an image modulator, and ii. at each point of the surface of the image modulator a more uniform filling of the available angular space. Embodiments of the present invention use a laser light source for use with an image modulator, the light source emitting light with multiple wavelengths for at least one primary color and a light integrator system that for each of the wavelengths is adapted to provide: i. a substantially uniform brightness across the surface of the image modulator, and ii. at each point of the surface of the image modulator a more uniform filling of the available angular space.
