ABSTRACT:
Color optical output apparatus comprising a color dependent mirror and a pair of optical spacial modulator arrays arranged to deflect light incident thereon, the arrangement being such that an incident polychromatic beam is split by said mirror means into two spectral components, one directed to each array, and said mirror means is arranged also to receive and combine deflected beams from each array to produce a combined optical beam, the spectral response of the mirror means being the same during splitting and combining.
