The Goal of this STTR is to develop a high speed, high power, waveguide based modulator (phase and amplitude) and investigate its use as a pulse slicer. The key innovation in this effort is the use of potassium titanyl phosphate (KTP) waveguides making the high power, polarization based waveguide amplitude modulator possible. Furthermore because it is fabricated in KTP, the waveguide component w ...

Innovative Imaging and Research, a small technology development company, has teamed with the University of Southern Mississippi Instrument and Cryogenics Research Laboratory to integrate existing NASA Stennis Space Center heritage cryogen level monitoring technology with noncontact optical methods and advanced signal processing to create a 21st century liquid cryogen level measurement technique. ...

Situational Awareness is the key element of performing safe and effective operations, and the space vehicle operations carried out by NASA is by no means an exception to the rule. Astronauts and flight controllers need to maintain awareness of the situation in the space vehicles, robots, habitats, Mission Control Center, and other systems. NASA has devoted and continues to devote a significant am ...

Single photon sources and detectors hold the key to achieving success in several quantum communication and computation applications. Many of these goals can be achieved with the realization of low-loss high-speed switching for single photons. AdvR proposes a unique implementation of an electro-optic (EO) deflector with ideal properties for single photon switching. The device operates on the pri ...

This NASA Phase I SBIR effort proposes to establish the feasibility of significantly improving coupling at fiber to waveguide interfaces for the manufacture of low loss fiber coupled components being developed for several NASA lidar based initiatives, including LaRC's HSRL program. Efficient and robust coupling of single mode fibers to optical waveguides is essential to the performance and m ...

For NASA missions requiring active control of segmented mirrors, optical trusses and booms, coherent, laser-based approaches such as CW laser interferometers have been preferred because they can provide very high resolution relative position measurements. Other approaches, such as multi-color interferometers can provide absolute range measurements. However, neither technique can measure multiple ...

This project develops a nutrition program, MenuChoice©, for community-based group homes for persons with intellectual or developmental disabilities (IDD). Adults with IDD experience poorer nutritional health and more nutrition-related secondary conditions than adults without disabilities. These conditions are preventable and modifiable through a safe, healthful diet, but multiple challenges precl ...

Icing is one of the most significant hazards to aircraft. There is still much research to be completed with regard to developing remote-sensing technologies for accurately identifying where icing conditions exist in clouds. There is a need to provide in-situ measurements of cloud liquid water content to validate the remote measurements.Anasphere, Inc. proposes to develop a modernized version of ...

Flux measurements of trace gases and other quantities, such as latent heat, are of great importance in scientific field research. One typical flux measurement setup involves placing measurement equipment (sonic anemometers and associated sensors or samplers) on rigid towers (rigidity being required to provide a stable platform for the sonic anemometers). These towers are relatively immobile, and ...

Dropsondes are one of the primary in-situ measurement tools available to research aircraft and Unmanned Aerial Vehicles (UAVs). Unlike sensors mounted on aircraft, dropsondes allow a vertical profile of the atmosphere to be taken below the aircraft. A guided dropsonde which could glide away from the launch aircraft will allow profiles to be taken away from the aircraft flight path, and would off ...
