摘要:
A microactuator, or micromotor, (60) and method for making it are presented such that a symmetrical build up of material is performed on opposite sides of a substrate. This reduces mechanical stresses in the device. In its construction, respective layers of circuit portions (108, 110) are built on each side of the structure, thereby eliminating the need to stack complex patterns. Stacking one complex pattern on top of a similar pattern is difficult because the surface, which is the base for subsequent layers, is not flat. The photolithography process that forms these patterns is not very forgiving to non-flat surfaces. Avoiding the stacked layers also allows thicker conductors to be considered for each circuit. Thicker circuits increase current carrying capacity, which in one of the key variables increase the power of the micromotor.

The present invention concerns an optic projecting technique for a projecting system comprising a housing and a projector unit, the projecting system comprises a housing and a projector unit, wherein the housing is provided with a display screen and a plurality of optic elements in the housing; the system is characterized in that: the projector unit is placed on the back of the housing in favor of detachment and displacement; when the projector unit projects optic images into the housing, the images from the projector are reflected by the optic elements and projected to the rear side of the display screen; when the projector unit is placed outside of the housing, it directly projects the optic images to the display screen at a suitable distance away, thus a dual projecting system for rear projection and front projection can be is formed.

A phase shift illuminator (700) is comprised of a light source (704) and a phase modulator (716), typically a flexure beam micromirror array, which transversely modulates the incident light beam. When a flexure beam micromirror array is used as the phase modulator (716) a polarizing beam splitter (712) and a quarter-wave plate (714) are used to separate the incident and reflected light beams. The phase modulated light beam (720) from the optical illuminator may be used in optical lithography by passing the light beam through a lithography mask (724), typically after the light beam is phase modulated, and focusing the light beam onto a target wafer (726).

An image simulation system 20 for testing sensor systems 26 and for training image sensor personnel wherein synthetic image data is generated by a scene generator 21 and projected by an image projector 23. The image projector 23 uses a digital micromirror device array 27 to modulate the incident energy and create an image. Four modulation schemes are discussed including digital pulse-width modulation, phase contrast modulation, full complex modulation, and analog modulation. The digital pulse width modulation technique will typically require synchronizing the image sensor and the image projector. Phase contrast modulation, full complex modulation, and analog modulation do not require synchronizing the image projector 23 and the sensor system 26. Phase contrast modulation and full complex modulation have the capability to produce phase information within the image. The image simulation system 20 can produce high contrast images and is more flexible than prior art system.

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 optical beams from one optical fiber to another. A mirror assembly (41) includes a single body of silicon comprising 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.
