Abstract:
1. A lighting system that provides a selected, variable selected spectral output and wavelength dependent intensity distribution, the lighting system comprising: a) a high output light source and an aperture wherein the high output light source is focused on the aperture and the aperture transmits light from the light source along a light path in an image of the aperture; b) a spectrum former downstream from and optically connected to receive the image of the aperture and is configured to provide a spectrum from the image of the aperture; and c) a pixelated spatial light modulator located downstream from and optically connected to the spectrum former, the pixelated spatial light modulator configured to pass desired light from the spectrum former to select a segment of light, wherein the pixelated spatial light modulator is operably connected to at least one controller containing computer-implemented programming that controls an on/off pattern of pixels in the pixelated spatial light modulator to provide a variable desired segment of light consisting essentially of a variable desired selected spectral output and a desired wavelength dependent intensity distribution.
