Patent ID: 8162483

Claim:
A light projection system comprising: an image forming subsystem configured at least to output a plurality of different color channels of light, the image forming subsystem comprising a plurality of light source subsystems each configured at least to generate a single color channel of the plurality of color channels output by the image forming subsystem, each light source subsystem comprising a plurality of lasers; and a light-intensity-correction subsystem configured at least to: determine laser light intensities output by individual lasers in each light source subsystem, control each light source subsystem to change a light intensity of an individual laser if an absolute value of the corresponding determined laser light intensity deviates from a predetermined laser light intensity by a first threshold amount; determine a color channel intensity for each of the plurality of color channels; control each light source subsystem to change a light intensity output therefrom if an absolute value of the corresponding determined color channel intensity deviates from a predetermined color channel intensity by a second threshold amount; determine a white point of the plurality of color channels; and control the light source subsystems to change an intensity of one or more of the plurality of color channels if an absolute value of the determined white point deviates from a predetermined white point by a third threshold amount.
