Award Data

Passive microwave sensors aboard satellites provide valuable information regarding weather conditions by measuring atmospheric attenuation over a broad range of frequencies from 0-200 GHz. Additional ground-based sensors are desirable to provide complementary upward looking measurements that can be used to refine existing attenuation models. Operating over such a large bandwidth, however, places ...

The proposed SBIR research (Phase I and II) is devoted to developing a laser-based acousto-ultrasonic system for inspection of sealed containers. The system represents a promising technology for improving safety management in anti-terrorism and treaty compliance operations. The system will use a pulsed laser to excite the container and a laser Doppler vibrometer for long stand-off vibratory (ult ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

NIST has developed an ultraviolet weathering device ¿ SPHERE (Simulated Photodegradation via High Energy Radiant Emission) based on integrating sphere technology that is used to accelerate the degradation of polymeric materials. SphereOptics is a manufacturer of integrating spheres and has experience in developing high radiance output uniform sources based on sphere technology. Given its manufa ...
