PHOTONIC DEVICES HAVING DEGENERATE OR SPLIT SPECTRAL BAND EDGESTech for Transfer PatentSale 08-10-2014 University researchers have developed a photonic device configured to display photonic band gap structure with a degenerate or a split band edge. Electromagnetic radiation incident upon these photonic devices can be converted into a frozen mode characterized by a significantly increased amplitude, as compared to that of the incident wave. The device can also be configured as a resonance cavity with a giant transmission band edge resonance. Application: This invention allows one to drastically enhance the performance of existing active electromagnetic elements, such as nonlinear and active materials, as well as creating much more efficient resonance cavities.

NANOMECHANICAL PHOTONIC DEVICESTech for Transfer PatentSale 08-10-2014 The present invention relates to devices which operate on gradient optical forces, in particular, nanoscale mechanical devices which are actuable by gradient optical forces. The optical force is one of the most fundamental properties carried by light. This force is generally considered too small for macroscopic practical use. Yet in the microscopic world, optical tweezers have been widely used to manipulate atoms and micron-sized dielectric particles in free space. Harnessing optical forces on chip would bring transformational advances in electromechanical systems by offering efficient and ultrahigh bandwidth optical coupling to the sub-micron scale devices.

FIELD-SEPARATED MULTI-PATH TELESCOPETech for Transfer UAH_techsell 19-05-2015 Two-mirror telescope designs image a small well-corrected circular field-of-view (FOV) about the optical axis of the two mirrors. Three-mirror designs use a primary, secondary, and tertiary mirror to increase the range of the FOV, but this range is still limited. One type of three-mirror telescope has a very well-corrected annular zone FOV and does not form a complete circle; image quality at the center can be considerably worse.

CLOSE RANGE TARGETING SCOPE CORRECTORTech for Transfer UAH_techsell 19-05-2015 Long range target practice requires a wide spread of areas and distance, due to the conventional reticle scope, which magnifies the target from afar. However, the conventional device could prove a hassle in a limited environment, especially for target practice within a simulation program within a closed room. The reason is that if a target is too close to aim, it alters the relative positions of the reticle and target, resulting in faulty aiming. Adaptive Optics Tell me more |

COMPACT THERMAL NEUTRON IMAGING SYSTEM USING AXISYMMETRIC FOCUSING MIRRORSTech for Transfer UAH_techsell 19-05-2015 Thermal neutron imaging is a powerful method of studying man-made or natural materials and structures. Unfortunately, high-resolution neutron imaging commonly requires high-flux reactors, which are not easily accessible, and many neutron instruments are limited by the availability of neutron fluxes. The challenge for progress in neutron optics and instrumentation is the development of efficient neutron optical components, such as the commonly used mirrors and lenses.

ADAPTIVE ATTENUATING SPATIAL LIGHT MODULATORTech for Transfer UOC__techsell 08-06-2015 It is often desirable to control the contrast of specific regions of an image in a variety of applications despite extreme variations in brightness of light emanating from neighboring regions. For example, intensified CCD cameras used for night vision suffer from blooming and halo, meaning that distant, bright sources of light look larger and closer than they are, because the excess charge on the CCD "spills over" into adja- cent areas. This results in distortion and/or masking of the portion of the image originating near the bright light source. Adaptive Optics Light sources Tell me more |
