Abstract: A projector includes a laser light source and a glass wheel. The laser source is configured to generate laser light. The glass wheel is optically coupled to the laser source. The glass wheel includes a first surface and a second surface. The first surface is configured to receive the laser light, and includes a light direction device optically coupled to the laser source. The second surface is opposite the first surface and is configured to emit light. The second surface includes a first arc of a phosphor deposited at a first distance from a center of the glass wheel. The light direction device is configured to direct the laser light to the first arc of the phosphor. The second surface also includes a second arc of the phosphor deposited at a second distance from the center of the glass wheel.

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.
