The proposed research comprises design, analysis, and ultimate fabrication and operation of a microfabricated array of quadrupole mass spectrometers (QMS). The design capitalizes on recent advances in micro-electro-mechanical systems (MEMS) and molecular-beam-epitaxy (MBE) technology so that the device can be mass-produced on a chip. In addition to analyzing a single element QMS in Phase 1, invest ...

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 ...

Session Control technology, which tracks, controls, and directs all media sessions. Beyond Access proposes to provide feasibility into not only the core Session Control technology, but also an enabling software platform to connect, discover, and manage complex many-to-many multi-modal interaction sessions.

This project is to assess the feasibility of an instrument to provide energy-filtered electron images of a specimen at least 10mm by 10mm in size, operating over a 50-900eV energy range and suitable for NEXAFS chemical imaging. The applicant proposes to demonstrate feasibility by delivering a suitable electron-optical design along with calculated performance characteristics. Knowledge of the exist ...

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 ...

Group III-nitrides with their wide bandgap properties are one of most promising materials not only in opto-electronics but also in high power and high temperature electronics. A critical issue in device applications of the nitride materials is the metal ohmic contact, which seriously limits the performance and efficiency of nitride-based devices. Finding suitable low-resistance Ohmic contacts for ...

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 ...

This proposal addresses the need for accurate, self-referencing temperature measurement in cancer treatments such as hyperthermia and RF ablation. In all of these therapies, conventional metallic sensors such as thermocouples are unattractive because they either interact with the heating field (hyperthermia, RF ablation) or have excessive thermal conductivity (cryoablation). Integrated Photonics T ...

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 ...
