The goal of this Phase I SBIR is to define a set of algorithms that will detect and characterize static man-made objects highly obscured by foliage within multi-view, multi-channel optical data collected passively from UAVs or other aerial platforms. The proposed algorithm stream will be constructed so as to comprehend and mitigate real-world interfering effects such as clouds, smoke and haze. Dur ...

Two distinct designs with performance characteristics for analyzers consistent with the solicitation requirements were delivered in Phase 1. The Phase 1 research and modeling results have been sufficiently conclusive to indicate feasibility of both designs. The more novel of the two designs is proposed: a hybrid magnetic/electrostatic analyzer that features very high collection and transmission ef ...

Fabrication of stable, nearly 100% internal carrier collection efficiency silicon photodiodes (AXUV diodes) for 1 nm to 600 nm photons was successfully demonstrated by us several years ago. Owing to their excellent characteristics, these devices are being used by NIST as transfer standards in 5 nm to 250 nm range and aboard SOHO, SNOE and TIMED instruments for the EUV solar spectrum studies. Alt ...

An innovative optical system with 500X higher ¿tendu and spatial resolution will be designed for CCD-based bistatic lidar. A 100¿ vertical field of view is required to image the laser beam from the ground through the boundary layer, but only a few degrees are required in the horizontal direction. The proposed design is based on dividing the vertical field of view into N sectors, using 1D rasteri ...

In this Phase I SBIR, Nomadics will build on our past experience with micro-structure resonators and quartz-based sensors to develop a pressure sensor suitable for high pressure applications such as oil and gas industry applications. In the Phase I work, the outstanding measurement resolution of our sensing technology will be demonstrated and the feasibility of this technology for pressure sensing ...

A new type of THz photomixer will be developed using a submicron interdigitated-electrode structure fabricated on an Eras:GaAs ultrafast photoconductive layer, an AIAs heat spreader and an AIGas/AIAs dielecric mirror. The Eras:GaAs-based photomixer will provide extremely wide tuning bandwidth (>1 decade) and a continuous-wave output power of roughly 10 microwatt around 100 GHz, at least 1 microwat ...

Wavelength dispersive spectrometers (WDS) are widely used in both scanning electron microscopes and scanning transmission electron microscopes for x-ray elemental analysis and mapping. The WDS systems are typically used to detect x-rays in the 100 eV - 2000 eV energy range, for chemical analysis of elements Be through P. Despite the excellent energy resolution of the WDS systems, they rely on gas ...

We propose to develop the technology to address the need for better harmonic reference devices in order to support the field of non-linear device characterization. Superconducting delay lines can be used to generate nonlinear harmonic signals with a known magnitude and phase relationship to the fundamental signal. In order to make such a reference device, we will need to make superconducting delay ...

Modern technology has significantly impacted advanced fire alarm systems. As the sophistication of new devices increases, so has the quantity of data they are capable of collecting. However in current alarm systems only a small portion of the available information is used. Without the continuous utilization of data from each detector it is difficult to gain an accurate view on the fire's progressi ...
