摘要： A micromachine and a manufacturing method are provided for a micromachine that has a dynamic first microstructured portion serving as a drive portion, and a static second microstructured portion adapted to perform a switching function and which functions as an optical element. The second microstructured portion can be manufactured at least without complex steps, such as a silicon process, by forming a static second microstructure on the dynamic first microstructured portion, or in such a way as to be overlaid thereon by mold transfer. Thus, the microstructured portion of a complex shape can be easily formed with good reproducibility. When a plurality of elements are arranged in an array, similarly as in the case of a spatial light modulator, the stable reproduction thereof is achieved by the mold transfer. Thus, as compared with the case of manufacturing all elements in a silicon process, the probability of an occurrence of a defect is very low.

摘要： An optical switching device comprises: a light guide including a total reflection plane capable of totally reflecting light thereby transmitting the light; a switching part capable of, at a position where its extraction plane is in close contact with the total reflection plane, capturing evanescent light and reflecting the captured light thereby outputting it; and a driving part for driving the optical switching part. The light guide, the switching part, and the driving part are laminated in this order into a multilayer structure. The employment of the multilayer structure makes it possible to optimize the respective layers independently of one another. The extracted light does not pass through the driving part. This allows the driving part to be optimized so as to achieve an optical switching device capable of operating at a high speed with low power consumption. Thus, it is possible to provide a low-loss and high-contrast optical switching device using an evanescent wave, which can respond at a high speed.

摘要： A projector with high safety is provided by directly shutting down the laser beam production when normal scanning of the laser beam is not carried out, thereby reducing exposure to the laser beam. For this purpose, the projector is provided with a laser beam source (10) that outputs a laser beam and modulates the laser beam in a beam form based on an image signal, a scanning unit (30) that scans the laser beam output by the laser beam source (10) at least in one-dimensional direction, a scan driving unit (50) that drive controls the scanning unit by a first force, a retaining unit (40) that stops and retains the scanning unit at a predetermined position by a second force, and a light shielding unit (70) that shields the laser beam from the scanning unit (30) that is retained by the retaining unit (40). The scan driving unit (50) releases the scanning unit (30) retained by the retaining unit (40), and drives it when the first force is larger than the second force. The retaining unit (40) stops and retains the scanning unit (30) 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.
