Abstract:
A system includes: a phosphor configured to receive first light having a first color, to produce second light having a second color responsive to the first light, and to transmit at least a first portion of the first light; a color wheel comprising a first colored segment configured to transmit light having a third color and a second colored segment configured to transmit light having a fourth color; a light tunnel optically coupled between the phosphor and the color wheel configured to transmit combined light including least a portion of the first light and the second light; wherein the first segment is configured to transmit the third color as first transmitted light and the second segment to transmit light of the fourth color as second transmitted light; and a spatial light modulator configured to modulate the first transmitted light and the second transmitted light.
