The GHz-rate phase-stabilized fiber-laser frequency comb system is proposed to be used as a light source for coherent Fourier transform spectroscopy. The system will be developed based on our proprietary glass/fiber technology, which features a low-cost, robust, highly stable, mid-infrared light source that enables the development of a robust portable c-FTIR spectrometer for absorption measurement ...

Maritime asymmetric threat detection begins with an in depth comprehension of the tactical picture. Security lies in the ability to sense threats in all environments. Advanced Optical Systems, Inc. (AOS), together with partners Technology Systems, Inc. (TSI) and Raytheon IDS, have joined together to propose APSTAAT. APSTAAT is a system for autonomous persistent surveillance for the asymmetric air ...

Visually degraded environment (VDE) conditions pose a threat to Navy and Marine Corps helicopter operations during landings and troop insertions/extractions. Blinding dust clouds caused by rotor down-wash during low level flight can cause pilots to suddenly lose all visual cues. This loss of situational awareness (SA) creates significant risks from other aircraft and ground obstacles. According to ...

Advanced Optical Systems Proximity Operations Measurements System (POMS) for terminal guidance during Autonomous Aerial Refueling (AAR) provides relative position and attitude, all 6 Degrees of Freedom (DoF), in a manner similar to that sensed by a human pilot. POMS recognizes and locates features on the tanker and drogue with a sensor on the UAS and converts the relative location of those feature ...

Our baseline concept is to precisely locate the aircraft relative to the ship, using a cooperative 6 Degree of Freedom (6-DoF) optical sensing system. The system also identifies the ship though time modulation on the sensing system. The 6-DoF information is combined with a database of the ship’s geometry to provide Object Proximity Warning data to the Ground Proximity Warning System. The system ...

Multi-channel array manifolds are required for wideband AESA applications. In modern solid-state AESA arrays, MMIC-based T/R modules generally utilize digitally-controlled phased shifters to steer the beam on transmit and receive. The given phase value is only accurate at one frequency, and so for wide bandwidths of several hundred MHz (at X-band for example), the beam does not get formed properly ...

Key obstacles to extending OFDM to wireless links and networks at high-frequencies and dynamic channels are inherent low performance to Doppler and power amplifiers operation with high back-off. Other significant obstacles are multipath and impulsive noise. PEARL-OFDM combines a layered architecture with technologies that mitigate such obstacles and enable full-range rates that maximizes connectiv ...

Current research tools to understand tumor cell migration and metastases are limited to linear gradients or constant flow across cells skewing results. Researchers at the National Institute of Standards and Technology developed a tool called the microfluidic palette which exposes cells to chemical stimuli in a static environment overcoming the limitations above. Several improvements are necessary ...

Visual Landing Aids are required for visual acuity to safely guide aircraft during night and/or low visibility aircraft operations, for general lighting and navigation. The current generation of VLAs was designed to withstand loads associated with existing aircraft. Future aircraft are expected to generate more severe exhaust loads that could threaten the integrity of these lighting fixtures. Indi ...

We propose the development of a compact broadband underwater cylindrical transducers with integrated tuning networks and power amplifiers for Mobile Acoustic Counter Measures. There is a need for cost effective transducers that are broadband and have broad-beam coverage. BTech has designed and built improved counter measure transducers as well as acoustic modem transducers using both PZT materials ...
