A single-shot spectral imager or imaging system which acquires multiplexed spatial and spectral data in a single snapshot with high optical collection efficiency and with the speed limited only by the readout time of the detector circuitry. The imager uses dispersive optics together with spatial light modulators to encode a mathematical transform onto the acquired spatial-spectral data. A multitude of encoded images is recorded simultaneously on a focal plane array and subsequently decoded to produce a spectral/spatial hypercube.

A method for lightpath restoration in a reconfigurable optical network comprises the steps of naming each network addressable element in said reconfigurable optical network, determining current topology in said reconfigurable optical network, determining current resources in said reconfigurable optical network, requesting establishment of a lightpath, requesting reservation of restoration capacity, allocating the lightpath, and reserving the restoration capacity. Also disclosed is a method for lightpath restoration that comprises the steps of reserving restoration capacity, detecting transmission failures in the reconfigurable optical network, handling exceptions as a result of transmission failures, and allocating transmission capacity.

A resolution proportional digital zoom system comprises a CCD imaging device with over a million pixels resolution. A standard fixed-1X optical lens is fitted to the imager. A communication channel with a limited bandwidth is used to transmit video. Such bandwidth is substantially less than the imager's full resolution times its frame rate. A user is provided with controls to pan and zoom within the imager's field of view. The pixel resolution is proportionally controlled such that video output data rate on the communication channel is optimal and held within maximum limits at any pan/zoom setting.

The projection display system has a projection system having a plurality of polarized light modulators, each modulator generating a light-component-specific image associated with one of the light components. The projection display system also has a projection lens for projecting an image combined from the light-component-specific images from the modulators. The present invention also provides a polarization converter for use with a light source that generates a light beam having at least two light components. The polarization converter comprises an optics array capable of separating the light beam into at least one light component having a polarization that is different than another light component.

A device for recording images on a printing form, including an array of light sources and imaging optics for generating (n.times.m) imaging spots on a printing form, which is distinguished by the array of light sources including an array of mutually independently controllable VCSEL light sources. One specific imaging spot may be formed on the printing form by combining the light emitted by a subarray of the VCSEL light sources. Due to the advantageous beam properties of VCSEL light sources, such as the small divergence and negligible astigmatism, the device for recording images on printing forms is especially advantageous for use in a printing-form imaging unit or in a print unit.

A display system for a head mounted device that provides a wide field-of-view image to the user. The system may use a pair of displays angled relative to one another, and a lens or lenses between the displays and the user's eyes to generate a wide field-of-view image. Lenses may be for example gradient index lenses, Fresnel lenses, or holographic optical elements in order to provide significant and complex bending of light across the field of view with relatively thin lenses. The system may provide lower resolution images at the periphery of the user's field of view, using for example light emitting elements at the periphery that are directed by the lens or lenses towards the outside edges of the field of view.

An opto-electronic image magnifying system. The magnifiying system includes: a light source (38, 39) which illuminates an object to be viewed; a miniaturized opto-electronic magnifier module (MOM), made of a lens (31) and a photodetector array (32), which receives the light from the illuminated object; an electronic circuit (34) which receives the signal from the MOM; a video-monitor (35) which receives the magnified signal from the electronic circuit and displays the image. The opto-electronic image magnifying system allows for small objects or features of small objects to be observed in which historically compound microscopes or specialized optical viewing systems were required to observe the small objects.

A display system for a head mounted device that illuminates the peripheral regions of the user's field of view to enhance an immersive experience. The system may use peripheral light emitters to the left and right of one or more central displays. Peripheral light emitters may provide lower resolution images, or only with vertical resolution, corresponding to the user's lower resolution vision in these peripheral regions. Reflective surfaces and lenses may be used to direct peripheral light into desired shapes and patterns. Rendering of peripheral light colors and intensities at each peripheral pixel may use approximations for improved performance since users may not be sensitive to precise color values in the peripheral regions.

A projection apparatus (10) has an LC modulator panel (60) with photoresponsive layer (316), segmented into a first, second, and third portion, each spatially separated. An image writing section (120) forms a first, second, or third image within the corresponding portion of the LC modulator panel by scanning successive lines of image writing light to energize the photoresponsive layer. The image writing section has at least one grating electromechanical system for modulating a narrow-band light source (70) by providing diffracted and non-diffracted orders and a scanning element (98) for directing a line of light toward the LC modulator panel to energize the photoresponsive layer. An illumination section (130) directs the illumination beams for modulation by the LC modulator panel. Polarizing beamsplitter (24r, 24g, 24b), polarize and direct the illumination beams toward the LC modulator panel and directs modulated light toward projection lens (32).

The present invention provides a transmissive Spatial Light Modulator with fast response speed and higher brightness using micro-windows having switching transistors on said window so that the fill factor of light transferring area can be maximized. Conventional systems have transistors out of windows which substantially reduce the area to pass incoming light, because transistors are usually opaque and block light transmission. Transmissive Spatial Light Modulator requires simpler and smaller optics than reflective Spatial Light Modulator.

Furthermore, the system consists of an optional accelerometer, resident on the receiver, to dynamically adjust the image sensor frame rate.
