Patent ID: 7125123

Claim:
A display system comprising: an illumination source for projecting light toward an optical target; a color filter system configured to rotate about a first axis and disposed in a path of travel of the light projected by the illumination source, wherein the color filter system comprises: first and second co-centric multi-segment optical filters both configured to rotate about the first axis, wherein rotation of the first multi-segment filter about the first axis defines a first filter area for positioning in said path of travel, and wherein rotation of the second multi-segment filter about the first axis defines a second filter plane for positioning in said path of travel; and a moving mechanism configured to move the first and second co-centric multi-segment filters and the respective first and second filter areas in and out of said path of travel, such that moving the first filter area in said path of travel, removes the second filter area from said path of travel, wherein the first and second filter areas form first and second filter cylinders respectively, wherein each of the first and second filter cylinders is at least partially hollow to receive the optical target.
