Deformable segmented MEMS mirror
A MEMS device having a deformable segmented mirror. The mirror includes a plurality of movable segments supported on a substrate using spring vertices, each vertex having a fixed plate and one or more springs. In a representative embodiment, three springs support each movable segment, where each spring connects the movable segment to a different spring vertex. The MEMS device also has a plurality of electrodes, each of which can be individually biased. A movable segment moves in response to a voltage applied to an electrode located beneath that segment while the deformed springs attached to the segment provide a restoring force. Due to the fixed plates, motion of each movable segment is substantially decoupled from that of the adjacent segments, which makes the shape of the segmented mirror relatively easy to control. In addition, segments in a deformable mirror of the invention can be displaced by a distance that is significantly larger than the maximum deformation amplitude for a membrane mirror of the prior art. The MEMS device can be fabricated using two silicon-on-insulator (SOI) wafers and an etch fabrication technique.

Camera capable of video and film shooting having optical viewfinder
A camera is capable of both silver-halide shooting, through which object images are recorded on silver-halide film, and video shooting, although its distance measurement device is placed substantially in the same way and its mirror box has substantially the same size as in ordinary single-lens reflex cameras. In this camera, a pellicle mirror splits the light flux having passed through a taking lens into a first light flux and a second light flux, and a rotatable mirror switches the subsequent path of the second light flux between the optical path for a third light flux and the optical path for a fourth light flux. The pellicle mirror, through its light flux splitting function, directs the first light flux to a silver-halide shooting system, and directs the second light flux to the rotatable mirror. The rotatable mirror, through its optical path switching function, either directs the third light flux to an optical viewfinder system, or directs the fourth light flux to a video shooting system.

Fabrication method of extreme ultraviolet radiation mask mirror using atomic force microscope lithography
InactiveUS20070054196A1Reduce pollutionReduce surface roughnessMaterial nanotechnologyNanoinformaticsExtreme ultravioletRadiation exposure
The present invention relates to a method for manufacturing a reflective multi-layered thin film mirror for an extreme ultraviolet radiation (EUV) exposure process that is one of the next generation exposure process masks using an atomic force microscope (AFM). This reflective multi-layered thin film mirror for extreme ultraviolet radiation (EUV) exposure process allows metal oxide structures with fixed height and width to be obtained using anodic oxidization phenomenon between the cantilever tip of a atomic force microscope and an absorber material during the patterning of an absorber layer on a multi-layered thin film of a substrate, followed by forming the ultra-fine line width absorber patterns via etching of the metal oxide structure. Use of the manufacturing process of this invention is advantageous in manufacturing of extreme ultraviolet radiation exposure mask mirrors with high resolution and in manufacturing of reflective multi-layered thin film mirrors with minute absorber pattern sizes (less than 20 nm line width) compared to traditional manufacturing methods.

Magnetic membrane mirror
Described is a magnetic membrane mirror having a flexible membrane comprising a magnetic material and having a high reflectance. The flexible membrane is secured over a frame to enclose a volume between the frame and membrane. A transmembrane pressure is established to achieve a desired mirror shape or curvature. Curvature can be changed by modifying the transmembrane pressure by increasing or decreasing the pressure in the enclosed volume. An array of electromagnetic actuators generates individually-controlled magnetic fields to cause localized displacements of the mirror surface. The magnetic membrane mirror can be constructed with inexpensive components and can be used as a dynamic component in an adaptive optical system.
