Abstract
This invention pertains to a scene projection system and a method for projecting a scene that can simulate light temperature of above 2000 K. The system comprises of a light source part for generating light at a lower wavelength; a means part for individually controlling dynamic range, contrast, brightness, temporal characteristics and temporal dynamics of the light; a rare earth doped fiber part that re-emits the output light at a higher wavelength; and a means part for conveying light between its parts. The method comprises steps of generating light at a lower wavelength; individually controlling temporal characteristics, temporal dynamics, brightness and contrast of the light; passing the light through a rare earth-doped fiber; and re-emitting the light at a higher wavelength.
