Abstract
A projection system is disclosed that includes a light source, a spatial light modulator, and an optical filter. The light source is configured to generate a light beam having a spectral distribution spanning a set of primary colors. The spatial light modulator has an array of pixel elements. Each pixel element is configured to receive a portion of the light beam and to output a modulated light beam with a spectral peak defining one of the set of primary colors. The optical filter is configured to narrow the spectral peak.
