摘要： The light guide substrate 2 has mirror receiving grooves 24 and light guides. The light guides conduct light that is input into the input ports to selected output ports in accordance with the advance and retraction of the mirrors 31 with respect to the grooves 24. The actuator substrate 4 has mirrors 31 and actuators which place the mirrors 31 in a state in which the mirrors are drawn in toward the substrate 4, or a state in which the mirrors protrude from the substrate 4. The light guide substrate 2 and actuator substrate 4 are aligned using alignment marks and joined with a spacer 3 interposed so that the mirrors 31 retract from the grooves 24 when the mirrors 31 are drawn in toward the substrate 4, and so that the mirrors 31 advance into the grooves 24 when the mirrors 31 protrude from the substrate 4. This alignment is performed in a state in which all of the mirrors 31 are drawn in toward the substrate 4.

摘要： A movable plate is fastened to a substrate via flexure parts and can move upward and downward with respect to the substrate. The substrate serves as a fixed electrode. The movable plate has second electrode parts which generate an electrostatic force between these electrode parts and the substrate by virtue of a voltage that is applied across these electrode parts and the substrate and a current path which is disposed in a magnetic field, and which generates a Lorentz force when powered. A mirror advances into and withdraws from the optical path. When the movable plate moves from the lower position in which the electrostatic force is increased to the upper position, the control part controls the current so that the Lorentz force is generated in a downward orientation and gradually decreases while the movable plate moves from an intermediate position to the upper position.

摘要： A movable plate 21 is fastened to a substrate 11 via flexure parts 27a and 27b, and can move upward and downward with respect to the substrate 11. The substrate 11 also serves as a fixed electrode. The movable plate 21 has second electrode parts 23a and 23b which can generate an electrostatic force between these electrode parts and the substrate 11 by means of a voltage that is applied across these electrode parts and the substrate 11, and a current path 25 which is disposed in a magnetic field, and which generates a Lorentz force when powered. A mirror 12 which advances into and withdraws from the optical path is disposed on the movable plate 21. When the movable plate 21 is caused to move from the lower position in which the electrostatic force is increased to the upper position, the control part controls the current so that the Lorentz force is generated in a downward orientation and gradually decreases while the movable plate 21 is moving from an intermediate position to the upper position. As a result, the mobility range of the movable part can be expanded without applying a high voltage or sacrificing compact size, and the power consumption can be reduced; furthermore, the reliability in the case of long-term operation can be increased.

摘要： Radiation detectors are disclosed that include at least one element (pixel). In a pixel, a desired positional relationship between two “effecting” elements is maintained regardless of changes in temperature or other prevailing variable. The detectors can be “electrical capacitance” or “optical-readout” types. A pixel of the electrical capacitance type includes two electrodes (reference electrode and response electrode) that face each other and have a set gap therebetween. The electrodes are attached to respective displaceable members (configured as thermal bimorphs) having identical structures. A pixel of the optical readout type includes a half-mirror and a reflector that face each other and have a set gap therebetween. The half-mirror and reflector are attached to respective displaceable members. Radiation is absorbed by a radiation absorber that transfers the heat to certain displaceable members that bend to tilt accordingly. Other displaceable members are not heated and do not bend. The displaceable members are formable simultaneously during respective fabrication steps.

摘要： Optically readable radiation-displacement conversion devices and image-rendering apparatus that incorporate same are disclosed. Also disclosed are related methods for detecting images and rendering images using such devices and apparatus. Such devices, apparatus and methods allow improved accuracy and sensitivity of radiation detection without having to use a cooler. A representative conversion device includes a substrate and a suspended portion attached to the substrate via a leg portion. The conversion device includes a radiation-absorbing film that receives and absorbs and incident invisible radiation (e.g., UV, IR, or X-rays) and generates heat from the absorbed radiation. The suspended portion includes a displaceable member that exhibits a displacement with respect to the substrate. The displacement also imparts a change to an incident readout light flux in accordance with the magnitude of the displacement. The change to the readout light is detected and used to form an image.
