This invention has incorporated projective optics and phase conjugate material thus eliminating the requisite use of an external phase conjugate material to provide a see-through head mounted projective display. A key component of the invention is the use of optical imaging technology in combination with projective optics to make this revolutionary technology work. In previous head mounted projective displays the phase conjugate material had to be placed in the environment to display images, but...

Plasma discharge sources for generating emissions in the VUV, EUV and X-ray spectral regions. Embodiments can include running a current through liquid jet streams within space to initiate plasma discharges. Additional embodiments can include liquid droplets within the space to initiate plasma discharges. One embodiment can form a substantially cylindrical plasma sheath. Another embodiment can form a substantially conical plasma sheath. Another embodiment can form bright spherical light emission ...

Transmissive liquid crystal displays having response time that can be approximately 2 to approximately 3 times faster than conventional displays. The displays adjust the rubbing angles to above approximately 20 degrees and preferably between approximately 30 and approximately 40 degrees. The displays have fast response times, enhanced brightness and increased gray scale linearity while maintaining wide viewing angle.

An ammonia synthesis process and apparatus are provided which are energy efficient and minimize greenhouse-gas-emission during the processing of natural gas and air. In the process a stream of natural gas is divided into two streams, one of which is mixed with air and ignited to provide heat for the thermal decomposition of natural gas into hydrogen and carbon and also to provide deoxygenated nitrogen for an ammonia synthesis process. The process essentially prepares hydrogen and nitrogen on a l...

The subject invention relates to beam control prisms and the use of a beam control prism to modify the beam properties of light emitted from an edge emitting diode laser. The subject invention can utilize a beam control prism placed next to a diode laser bar. The subject beam control prism can have, for example, a curved surface and/or a high reflective coated surface for a diode laser wavelength. The curved surface can collimate the fast axis divergence and the mirror surface can change the bea...

An EUV radiation source that employs a low energy laser pre-pulse and a high energy laser main pulse. The pre-pulse generates a weak plasma in the target area that improves laser absorption of the main laser pulse to improve EUV radiation emissions. High energy ion flux is reduced by collisions in the localized target vapor cloud generated by the pre-pulse. Also, the low energy pre-pulse arrives at the target area 20-200 ns before the main pulse for maximum output intensity. The timing between t...

Systems and methods for measuring a pulse length (.tau..sub.0) of an ultra-short light pulse (P.sub.0) based on processing a number of substantially similar light pulses. The system includes an autocorrelation optical system adapted to receive the light pulses P.sub.0 and create from each light pulse two beams having an associated optical path length difference .DELTA.OPL. Providing a different .DELTA.OPL for each light pulse creates an autocorrelation interference pattern representative of an a...

A differential Shack-Hartmann curvature sensor for measuring a curvature including principal curvatures and directions of a wavefront. The curvature sensor includes a Shack-Hartmann sensor with an input beam and an optical element to split said input beam into three output beams traveling in different directions. Three lenslet arrays in each of the three beam paths produce corresponding Hartmann grids. A shearing device shears two of the three Hartmann grids in two perpendicular directions a dif...

A method and kit for detection of Mycobacterium Avium Subspecies Paratuberculosis (MAP) in blood and blood derivative samples from humans by culture and PCR. Technology can screen for MAP in blood samples from millions of patients having inflammatory and non-inflammatory bowel diseases, and the results are used to identify those patients with MAP for treatment by antibiotics. The method and kit can monitor and evaluate the outcome of therapy.

Disclosed are imaging systems and eyeglass-based display devices. In one embodiment, an imaging system includes an image source and a partial mirror that defines a non-rotationally symmetric surface, wherein the partial mirror reflects images generated by the image source to an eye of an observer.
