摘要： A scanning display device (10) directly scans a light source (12) along at least one scanning path, rather than scanning a light beam emitted from such source (22) along such scanning path. By scanning the light source a smaller, lighter weight scanner without a mirror can be used to achieve light source scanning along the desired scan path. A resonant cantilever (44) translates one or more point sources (e.g., one for a monochromatic display; red, green and blue for an RGB display). The cantilever motion is driven by an electromagnetic drive circuit or by a piezoelectric drive actuator (82). The light source is one or more light emitting diode point sources (42), one or more fiber optic point sources (62), or one or more light emitting polymer light sources.

摘要： An optical matrix switch station (1) is shown mounting a plurality of optical switch units (15, 17), each of which includes a mirror (29), moveable in two axes, for purpose of switching light beams from one optical fiber to another. A mirror assembly (41) is formed from a single body of silicon and comprises a frame portion (43), gimbals (45), mirror portion (47), and related hinges (55). Magnets (53, 54) and air coils (89) are utilized to position the central mirror surface (29) to a selected orientation. The moveable mirror and associated magnets along with control LED's (71) are hermetically packaged in a header (81) and mounted with the air coils on mounting bracket (85) to form a micromirror assembly package (99) mounted in each optical switch unit.

摘要： The present invention relates to a light sensing device for exciting and detecting an emission of secondary light, especially of fluorescent light, from a test sample (40), comprising a light producing device (20) for producing sensing light in the form of a single bundle of light rays (21), as well as a deflection unit (10) to deflect the sensing light in at least one modifiable direction in order to sense at least one partial surface of the test sample (40), an imaging unit to image secondary light emitted from the test sample, and a detection unit to detect the secondary light. Unwanted long sensing times occur during fluorescent examination of a test sample having a large sensing surface and high local resolution. In order to reduce sensing times while maintaining high local resolution of said test samples, the inventive light sensing device has a splitting device (110) to divide the single bundle of light rays into at least two bundles of light rays (22,23), thereby resulting in a sub-division into fields instead of the usual sequential sensing of the test sample, said fields being simultaneously sensed by several beams of light. Sensing time can thus be reduced according to the number of simultaneously sensed test sample fields.

摘要： A projective display system includes a light source (250), a display surface (282), and a two dimensional light modulator array (242) in an optical path between the light source (250) and the display surface (282). The two dimensional light modulator array (242) has a plurality of light modulators (244) arranged in rows to modulate light from the light source (250), with at least one row being susceptible to failure. To compensate for any failed rows, a redundant light modulator array (242) is provided, with modulated light output from the redundant light modulator array (242) being directed by an optical element (270) positioned to selectively substitute for at least one failed row of light modulators (244).

摘要： An integrated micro-electromechanical (MEM) optical resonator comprises a cantilever beam which is fixed to a substrate at one end and extends freely over the substrate at the other end, and a bimorph actuator stacked atop the beam at its fixed end. A reflective surface partially covers the top of the beam at its free end. The bimorph actuator comprises material layers having different thermal expansion coefficients. A DC-biased AC voltage connected across the actuator causes it to heat and cool as the current passing through it increases and decreases, creating a thermal bimorph effect which causes the cantilever beam and the reflective surface to oscillate in accordance with the varying current, preferably at the beam and actuator structure's fundamental resonant frequency. Combining the resonator with a light source and actuator excitation circuitry creates an optical scanner engine which delivers a scan angle in excess of 20 degrees and a scan rate of up to 2000 Hz, using a driving voltage of only 2 V p-p.

摘要： The invention relates to an electromechanical device which includes a first frame (50) having a first aperture therein, a second frame (52) suspended in the first frame, the second frame having a second aperture therein, and a plate (54) suspended in the second aperture. A first pair of beams (56) support the second frame (52) along a first axis relative to the first frame (50) so that the second frame rotates about the first axis. A second pair of beams (58) supports the plate (54) along a second axis relative to the second frame (52) so that the plate rotates about the second axis relative to the second frame. The first and second axes preferably intersect at a 90° angle. A first set of actuators (60) provides mechanical force for rotating the second frame (52) relative to the first frame (50) about the first axis. A second set of actuators (62) provide mechanical force for rotating the plate (54) relative to the second frame (52) about the second axis. Accordingly, the plate (54) can be independently rotated relative to the first axis and the second axis.
