Award Data

Photonic links and networks offer numerous advantages to analog RF systems including inherent wide bandwidth, a reduced size, weight and improved flexibility, and nearly lossless signal. Current all-electronic delay line systems based on microwave components suffer from high signal loss and dispersion as well as large size and weight. An efficient way to achieve true-time-delay beamforming is to u ...

Existing methods to provide cable orientation and array element localization in the Navy’s fixed and towed array systems and tethered unmanned vehicles rely on devices embedded in the cable itself, such as hydrophones, magnetic heading and orientation sensors, and accelerometers. These traditional sensors have power, weight, space, and EMI budgets within the cable that require design compromises ...

Results of the Phase I work showed that an advanced, compact Point Sensor can be built with good sensitivity for detection of both biological agents and chemical aerosol and vapor agents. This will be the first point sensor capable of this dual role. The

Frequency Agile Laser sensor has shown great promise in standoff detection of chemical and biological agents in the long wave infrared (LWIR) portion of the spectrum through several field trials in recent years. The fact that it is now possible to perform

An eye-safe optically pumped laser based on a gas-filled hollow optical fiber will be demonstrated to lase at both near infrared (IR) and mid IR wavelengths. These lasers will be the first in a new class of IR lasers, based on the combination of hollow-f

During the Phase I period, we have successfully developed and demonstrated all the major technical components to achieve the goal of providing seamless large scale display anywhere, anytime, for any content. Based on the solid foundation we have built from Phase I, we plan to improve and integrate various components to develop intelligent projectors that can be networked together to create a seaml ...

A fully functional widely tunable wavelength converter prototype operating from -40C to 100C at 2.5-10 Gbps, in a 5mm tall package, will be developed.

Remote ocean instrumentation often relies on floating buoys with sensors to acquire time series measurements such as ambient noise, acoustic tracking or communications. The operating lifetime of small remote buoys is limited by batteries (often to 12 - 24 hrs), and recharging is so inconvenient or impractical that many small sonobuoys are designed to scuttle themselves after about a day. The assoc ...

In the Phase I STTR, N08-T029 “Novel Fiber Optic Methods for Sensing Shape, Orientation and/or Heading of Undersea Arrays and Tethers” a concept was developed for a fiber optic sensing array and shape reconstruction algorithm to be used for situation awareness of flexible undersea cable structures. Undersea cable structures are deployed in environments unsuitable for direct in-situ observation ...

Acellent Technologies Inc. and Prof. F. G. Yuan at North Carolina State University (NCSU) are proposing to develop a Hybrid Distributed Sensor Network Integrated with Self-learning Symbiotic Diagnostic Algorithms and Models to determine materials state awareness and its evolution, including identification of precursors, detection of microdamages and flaws near high stress area or in a distributed ...
