The proliferation of nuclear and radiological weapons of mass destruction is a serious threat in the world today. The goal of this proposal is to develop a new, very low cost radiation detection technology that will be useful for detection and for surveillance of individuals who have been near radioactive materials. The technology can also be used for dosimetry, and will provide the technology for ...

A drop-in 3He-tube replacement technology for thermal neutron detection does not exist today. It is critical for homeland security and nuclear safeguards applications. In this program, Triton Systems proposes to develop a light-weight, large-area, high efficiency portable neutron detector for passive interrogation using an innovative gas detector structure. The resulting 3He-free thermal neutron d ...

As the warfighter is increasingly using more highly integrated instruments, e.g. a laser rangefinder (LRF) combined with a laser designator and an imager, the need to decrease the size of these components becomes more important. Compact small munition applications of rangefinders particularly place an emphasis on size of the optical front end. In order to make the transceiver more compact, speci ...

The technical objectives of this proposal are: 1) the design of high-index-contrast (HC) photonic-crystal (PC) THz, difference-frequency-generation (DFG) quantum cascade lasers (QCLs) with midinfrared pumps at 8 micron and 9 micron wavelengths; 2) design and demonstrate operation of a 4 THz DFG-QCL with the midinfrared pumps operating at 8 and 9 microns; and 3) Theoretically demonstrate the feasib ...

Recent demand for short-range communications has risen sharply for both the defense and commercial sectors. Tactical communications with a deployed sensor network require secure short-range communications and high network density to enable robust data fusion and collaborative sensing for enhanced situation awareness for the war fighters. The THz nano-radio technology being developed in this projec ...

Physical Sciences Inc. in cooperation with Colorado State University proposes to develop a compact infrared flash 3D imaging sensor employing compressive sensing (CS) concepts. The CS 3D sensor offers a combination of high range resolution (cm), high point cloud density (100100 format), and fast 3D image frame rates (30 Hz) in a low cost, compact form factor employing commercial off the shelf comp ...

Assured position, navigation and time (PNT) require constant vigilance against intentional and unintentional sources of coherent and non-coherent interference. The Global Positioning System (GPS) is especially vulnerable to attacks and must be defended through electronic protection (EP) measures such as anti-jam (AJ) and anti-spoof (AS). The proposed effort will design and demonstrate GPS-based at ...

ABSTRACT: The Triton team proposes to develop techniques for fabrication and characterization of high performance biofunctionalized field effect transistors (bio-FETs) for sensing applications. Nanoscale electronic materials such as silicon nanowires, carbon nanotubes and graphene are promising materials for biosensing applications. Field effect transistors (FETs) using nanomaterials have been de ...

ABSTRACT: We exploit recent advances in magnetoelectric/piezoelectric (ME/PE) composite materials to enable the development of efficient sub-wavelength radio frequency (RF) transmitting antennas. With these materials will be possible to achieve high dielectric permittivity and magnetic permeability, slow electromagnetic propagation and low RF loss tangents. Together, these special properties m ...

ABSTRACT: Two accelerating trends in military aircraft design and development are apparent: (1) increasing system capabilities in terms of weapon systems, ISR payloads, guidance, navigation and control (GNC), etc., enabled by ever-smaller and evermore capable electronics; and (2) reduction in overall size and available space for auxiliary equipment (and associated wiring, etc.) to measure and asse ...
