Claim Text:
1. A light-output system, for forming a controllable pattern of illuminated spots in a distant projection plane, said light-output system comprising: a plurality of individually controllable light-output devices arranged in an array of light-output devices with a light-output device pitch, wherein each individually controllable light-output device comprises a plurality of light-sources; and an optical system arranged between said array of light-output devices and said projection plane, said optical system being configured to project light emitted by said array of light-output devices in said projection plane as a projected array of the illuminated spots having a projection pitch being larger than said light-output device pitch; wherein each of a first device and a second device of said individually controllable light-output devices includes at least a respective first light-source configured to emit light having a first characteristic and a respective second light-source configured to emit light having a second characteristic that is different from said first characteristic; wherein said system is configured such that a majority of a first light spot having said first characteristic formed by said first light-source of said first device and a majority of a second light spot having said second characteristic formed by said second light-source of said second device overlap on said projection plane to form one of the illuminated spots wherein the plurality of light-sources in a given one of the plurality of light-output devices are spaced apart by a distance Δ where n is an integer 1, 2, 3, . . . , and z
