    摘要: A projector that includes a laser beam source that outputs a laser beam that is modulated based on an image signal and a screen on which the light beam is projected. The projector also includes a scanning unit that scans the laser beam within a predetermined surface and a scan monitoring unit that monitors scanning of the scanning unit and outputs a result of the monitoring. The projector further includes a beam light supply stopping unit that controls the laser beam source so as to stop output of the laser beam based on the result of monitoring output by the scan monitoring unit.

    摘要: A projector includes a laser beam source that outputs a laser beam and modulates the laser beam in a beam form based on an image signal, a scanning unit that scans the laser beam output by the laser beam source at least in one-dimensional direction, a scan driving unit that drive controls the scanning unit by a first force, a retaining unit that stops and retains the scanning unit at a predetermined position by a second force, and a light shielding unit that shields the laser beam from the scanning unit that is retained by the retaining unit. The scan driving unit releases the scanning unit retained by the retaining unit, and drives it when the first force is larger than the second force. The retaining unit stops and retains the scanning unit at the predetermined position when the second force is larger than the first force.

    摘要: A space light modulating apparatus and a projector offer a smooth image without a light-shielding part. The projector includes a space light modulating apparatus that modulates incident light based on an image signal, and that outputs modulated light, and a group of prisms installed on output-side of the space light modulating apparatus. The space light modulating apparatus includes opening sections that are a plurality of pixels arranged in a matrix form and a black matrix placed between the opening sections. The group of prisms includes prism elements each of which has at least a refracting surface. Light from one of the opening sections is incident on at least one portion of the group of prisms. A direction of the refracting surface and a tilt angle are arranged so that an opening section image is guided onto a black matrix image on a screen a distance from the group of prisms.
