摘要： A projection device includes a light source, spatial light modulator, a control unit, and a shield. The spatial light modulator has a modulation part that modulates the phase of light emitted from the light source. The control unit divides the modulation part of the spatial light modulator into at least two regions and sets phase images of the target image in these regions. The light source is controlled to emit light onto the modulation parts with the phase images. The shield allows light from the image region for the desired image to pass through as projection light while blocking light from an unnecessary region, including ghost images.

摘要： A new projector design combines one spatial light modulator that affects only the phase of the illumination, and one spatial light modulator that only affects its amplitude (intensity). The phase-only modulator curves the wavefront of light and acts as a pre-modulator for a conventional amplitude modulator. This approach works with both white light and laser illumination, generating a coarse image representation efficiently, thus enabling, within a single image frame, significantly elevated highlights as well as darker black levels while reducing the overall light source power requirements.
