    Abstract: An illuminator for an imaging system using a spatial light modulator has first color laser light directed by a dichroic element to a first annular band on a rotatable member. The first band includes phosphor segments that respond to illumination by the first color light to emit second and third color light along a first path back to the dichroic element for output, and a light transmitting or reflecting segment that transmits or reflects the first color along the same or a second path back to the dichroic element for output. The output light is directed to a second annular band on the same or a different rotatable member. The second band includes filter segments corresponded to respectively selectively filter output light generated by the first band segments.

    Abstract: A projection light source has a source of laser light of a first color. A first member has first and second phosphor material segments respectively configured to emit light of second and third colors when illuminated by the laser light of the first color. A second member has first and second dichroic filter segments respectively configured to pass the light of the second and third colors emitted by the first and second phosphor material segments, while blocking light of the others of the first, second and third colors. Relative placements of the first and second members are synchronized to periodically align the first member with the laser light source and the second member with the first member, so that the first dichroic filter segment will pass the second color along a path at first time intervals when the second color is emitted by the first phosphor material and the second dichroic filter segment will pass the third color along at least a same portion of the path at second time intervals when the third color is emitted by the second phosphor material.

    Abstract: In described examples, a first TIR or RTIR element is arranged to introduce at least red light to a first spatial light modulator for modulation thereof, and a second TIR or RTIR element is arranged to introduce at least green light to a second spatial light modulator for modulation thereof. At least one of the first and second TIR or RTIR elements is arranged to introduce blue light to at least one of the first and second spatial light modulators, respectively, for modulation thereof: time-sequentially apart from the first spatial light modulator's modulation of the introduced red light, to an extent the blue light is so introduced to the first spatial light modulator; and time-sequentially apart from the second spatial light modulator's modulation of the introduced green light, to an extent the blue light is so introduced to the second spatial light modulator.

    Abstract: A system includes a spatial light modulator (SLM) and a circuit including a processor. The SLM includes pixel elements. The circuit is configured to convert M primary video signals to N multi-primary video signals. The circuit is configured to use a first multi-primary video signal to derive a first additive offset to a first primary video signal, to use the first multi-primary video signal to derive a second additive offset to a second primary video signal of the M primary video signals, to add the first additive offset to the first primary video signal, to add the second additive offset to the second primary video signal, and to derive a bit plane based on the first primary signal having the first additive offset added thereto and to transmit the bit plane to the SLM to selectively control on and off states of the pixel elements of the SLM.

The system includes a first optical path that includes the red LED, the red laser, the first filter, the second filter, and the lens, where the first filter has a filter response to transmit red light from the red laser and to reflect red light from the red LED. The system also includes a second optical path that includes the blue LED, the green LED, the second filter, and the lens, where the second filter has a filter response to transmit blue light from the blue LED, to transmit green light from the green LED, to reflect red light from the red laser, and to reflect red light from the red LED.
