摘要： An optical light valve system (10) for providing an amplified phase conjugated replica (S1*) of a potentially low intensity phase aberrated optical signal beam (S1) is disclosed herein. The optical light valve system (10) of the present invention includes a reference beam source (17) for providing a coherent reference beam (R) having first and second components of first and second polarization states, respectively. Further included is a signal beam source (15) for providing a coherent signal beam (S) of the first polarization state. An improved optical light valve (20) phase conjugates the second component of the reference beam in response to the aberrated beam (S1*).

Generally, the MQW NBRM SLM of the present invention comprises a MQW optical modulator (34) and driver means for driving the MQW optical modulator. The MQW NBRM SLMs of the present invention can be configured in a plurality of configurations. The driver and MQW optical modulator may be configured in hybrid or monolithic configurations. The MQW optical modulator can be operated in either transverse or longitudinal electric field modes. The MQW NBRM SLM structures can be operated using either electroabsorption or electrorefraction effects, and in transmissive or reflective modes. The structures are operable with different addressing and write-in mechanisms, including photo-activation and electronic addressing. Alternate embodiments have special features such as cascaded heterojunction MQWs and pixelized submicron metal mirror. The disclosed invention provides an improved, high speed, high resolution, semiconductor drive-compatible, spatial light modulator using multiple quantum wells.

摘要： A head-mounted display device (10) offers light weight, a low center of gravity, and low moments of inertia about the azimuthal and elevational axes of head movement. The display device (10) employs an angulated beam splitter mirror (16) disposed between a user's (22) eye (20) and an inner combiner surface (18a) of a visor (28). A projector (36) is carried laterally of the user's eye with a low center of gravity and a position close to the horizontal axis of elevational movement of the head. This projector (36) includes an image source (12) and a compact light-weight relay optics module (14) along with a projection fold mirror (30) disposed at eye level and laterally of the beam splitter mirror (16) to project image light to the beam splitter mirror (16). The beam splitter mirror (16) reflects the light onto the inner surface (18a) of the combiner (18) for reflection back through the beam splitter mirror (16) and to the user's eye (20). Alternative embodiments provide for color correction, or for mono-chrome image projection at even lighter weight. An alternative embodiment provides for both color correction and weight nearly as light as the monochrome version by use of diffractive lenses in the relay optics module.

摘要： An eye protection device 10 comprising a liquid crystal light valve 20 for providing an image of a scene. The light valve images the field of view under observation in a spectral range which matches the human eye. It will automatically reject a laser threat by simply absorbing the energy therefrom in the photoconductive layer thereof. Thus, the invention 10 provides a broad spectrum, zero response time, angle and polarization independent, sensitive eye protection device having a fast recovery time, high extinction coefficient and a high damage threshold. Hence, the invention is expected to be of significant utility to personnel operating in hostile environments.

摘要： SELF-COMPENSATING HYDROSTATIC FLATTENING OF SEMICONDUCTOR SUBSTRATES A semiconductive substrate (1), such as a silicon wafer, is mounted on a baseplate (3), for inclusion in an optical device such as a liquid crystal light valve. An optical flat (9) presses the top surface of the silicon wafer toward the baseplate and against a ring seal (5) surrounding a fluid adhesive (7). The fluid adhesive hydrostatically distributes the force of compression to guarantee optical flatness and selfcompensation for the amount fluid adhesive surrounded by the O-ring. The optical flatness of the semiconductor substrate is limited only by the flatness of the optical flat against which it is compressed. Parallel alignment of the optical flat (9), the substrate (1) and the baseplate (3) is achieved by reflecting a laser beam (20) through the semiconductive substrate and observing the interference fringes therein, while adjusting the relative alignment so as to maximize the distance between fringes.

摘要： Various optical modulation systems and methods are disclosed which are based upon modulating the refractive index of a nipi structure. The refractive index modulation is accomplished by applying a controlled voltage differential across the n-doped and p-doped layers of the structure. Staggered contacts to the layers are formed by conductive elements which extend through the structure. One of the elements establishes ohmic contacts with the n layers, and the other with the p-layers. When implemented as an optical spatial phase modulator, one of the nipi contacts is provided as a grid which divides the structure into a matrix of pixel elements, with the other contact comprising separate wires extending through each pixel. A spatial voltage pattern is applied to the pixel wires to inject charge into their corresponding layers, and thereby modulate the refractive indices of the pixels. This imposes a desired spatial phase modulation onto a readout beam transmitted through the nipi structure. Various guided wave applications are also disclosed in which a beam is transmitted through a nipi structure parallel to the n and p layers. The nipi sturcture is not divided into pixels, but rather has a common voltage differential between its n and p layers. The structure's refractive index is spatially modulated by varying this voltage differential, whereby the spatial voltage modulation is transferred onto the beam.
