A representative embodiment of the invention provides a projection system having a laser source that incorporates a tunable liquid lens and a spatial light modulator adapted to modulate light generated by the laser source to project an image on a viewing screen. The tunable liquid lens is adapted to vary focal length, alignment or position with respect to an optical element that is external to the lens, ability to diffuse light, and/or polarization rotation angle.
摘要:
A laser projector having a configurable spatial light modulator (SLM) adapted to display various spatial modulation patterns and redirect illumination from a laser to form an image on the viewing screen. The laser projector drives the SLM to change spatial modulation patterns at a rate that causes the corresponding sequence of projected images to fuse to mitigate appearance of speckle in the resulting fused image. The SLM can be designed to redirect the illumination using either diffraction or specular reflection of light from the displayed spatial modulation pattern. In one embodiment, the SLM is a MEMS device having an array of individually addressable mirrors supported over a substrate and adapted to move (e.g., translate and/or rotate) with respect to the substrate.

The present invention provides an apparatus. The apparatus, in one embodiment, includes an actuator located over a substrate, a movable feature located over and coupled to the actuator, and a layer of material located above the actuator and movable feature and not constituting part of a beam/spring associated with the movable feature, the layer of material configured as a reservoir having an interior capable of holding a liquid, the movable feature being exposed to the interior.

The present invention provides a process and an apparatus. The process, in one embodiment, includes providing a micro-electro-mechanical system (MEMS) device, the micro-electro-mechanical system (MEMS) device including an actuator coupled to a movable feature, sacrificial material fixing the actuator and movable feature with respect to one another, and a layer of material located over the actuator, movable feature and sacrificial material. The process may further include removing only a portion of the layer of material to expose the sacrificial material, and subjecting the exposed sacrificial material to an etchant to release the movable feature.
摘要:
A MEMS device having a movable mirror and a movable actuator plate mechanically coupled together such that a relatively small displacement of the plate results in mirror rotation by a relatively large angle. In a representative embodiment, the mirror and actuator plate are supported on a substrate. The actuator plate moves in response to a voltage difference applied between the plate and an electrode located on the substrate beneath that plate. One or more springs attached to the plate provide a counteracting restoring force when they are stretched from their rest positions by the plate motion. A spring attached between the actuator plate and the mirror transfers the motion of the actuator plate to the mirror such that, when the actuator plate moves toward the substrate, the mirror moves away from the substrate. A representative MEMS device of the invention configured with a mirror that is about 100 &mgr;m in length is capable of producing the mirror rotation angle of about 15 degrees using an actuator voltage of only about 50 V.

摘要:
A MEMS device having a deformable mirror. In a representative embodiment, the MEMS device includes a deformable membrane supporting a plurality of light-reflecting segments that form the deformable mirror. One or more actuators, at least one of which is configured to apply torque to a side of the membrane, are used to deform the membrane. Membrane deformation causes the segments to change orientation and thereby change the shape of the minor. A representative MEMS device of the invention enables segment displacements in two directions and thereby realizes effective mirror curvature values in the range from about −2 mm−1 to about +2 mm−1.
