摘要： A system and method comprise a light source; a spatial light modulator including a substantially transparent material layer and a phase modulation layer; an imaging device configured to receive a light from the light source as reflected by the spatial light modulator, and to generate an image data; and a controller. The controller provides a phase-drive signal to the spatial light modulator and determines an attenuating wavefront of the substantially transparent material layer based on the image data.

摘要： A novel high efficiency image projection system includes a beam-steering modulator, an amplitude modulator, and a controller. In a particular embodiment the controller generates beam-steering drive values from image data and uses the beam-steering drive values to drive the beam-steering modulator. Additionally, the controller utilizes the beam-steering drive values to generate a lightfield simulation of a lightfield projected onto the amplitude modulator by the beam-steering modulator. The controller utilizes the lightfield simulation to generate amplitude drive values for driving the amplitude modulator in order to project a high quality version of the image described by the image data.

摘要： Dual and multi-modulator projector display systems and techniques are disclosed. In one embodiment, a projector display system comprises a light source; a controller, a first modulator, receiving light from the light source and rendering a halftone image of said the input image; a blurring optical system that blurs said halftone image with a Point Spread Function (PSF); and a second modulator receiving the blurred halftone image and rendering a pulse width modulated image which may be projected to form the desired screen image. Systems and techniques for forming a binary halftone image from input image, correcting for misalignment between the first and second modulators and calibrating the projector system—e.g. over time—for continuous image improvement are also disclosed.

摘要： A novel spatial light modulator (SLM) includes a cover glass, and modulation layer, and a plurality of pixel mirrors, and separates unwanted, reflected light from desired, modulated light. In one embodiment, a geometrical relationship exists between the cover glass and the pixel mirrors, such that light that reflects from the cover glass is separated from light that reflects from the pixel mirrors and is transmitted from the SLM. In one example, one of the cover glass or the pixel mirrors is angled with respect to the modulation layer. In another example embodiment, the cover glass has a particular thickness, which introduces destructive interference between light that reflects from the top and bottom surfaces of the cover glass. In another embodiment antireflective coatings are disposed between optical interfaces of the SLM. In another embodiment, light from the SLM is directed through an optical filter to remove unwanted light.
