An innovative, super-miniature, fast-switching array-based photonic time delay device is being developed for the active electronically scanned-array (AESA) MDA and Navy radars. The design is based on the fast electro-optic effect, the super miniature fiber-lens collimation array, and the existing WDM photonic true time delay technologies. In Phase I Agiltron has successfully demonstrated the core ...

LongWave Photonics proposes a terahertz quantum-cascade laser based swept-source optical coherence tomography (THz SS-OCT) system for single-sided, 3D, nondestructive evaluation (NDE) of non-conductive materials. The THz SS-OCT system uses a frequency tunable QCL array to generate an interferometric signal between a reference mirror, and a sample. An algorithm is used to transform this signal in ...

The objective of this program is to characterize the upper atmosphere electrical environment so that the effects of this environment on high altitude airships (HAA) and other platforms intending to operate in this environment can be determined, and protection methods developed. This includes transient luminous events (TLEs), such as red sprites and blue jets and their associated electrical propert ...

This NASA Phase II STTR effort will develop domain-engineered magnesium oxide doped lithium niobate (MgO:LN) for LIDAR-based remote sensing and communication applications. Use of bulk and waveguide-based domain engineered MgO:LN will allow the manufacture of highly efficient and compact, wavelength conversion modules for second-harmonic generation (SHG), sum-frequency generation (SFG), and parame ...

The main objective of this Phase II STTR project is to develop advanced control algorithms that enable multiple autonomous agents to perform complex tasks in rapidly changing environment cooperatively. We plan to use the forest fire monitoring mission to demonstrate the benefits of the proposed technology. The mission concept involves using multiple Low Altitude Short Endurance (LASE) Unmanned Ae ...

Many future space missions involve formation flying spacecraft performing imaging, inspection, assembly, and servicing missions. Having multiple spacecraft in close proximity undergoing comparatively rapid maneuvers dramatically changes the nature of safe modes. No longer can a spacecraft just null its rates, point its arrays towards the Sun and phone home. Now, the faulty spacecraft must also ...

ProtoInnovations, LLC and Carnegie Mellon University have formed a partnership to commercially develop rover-autonomy technologies into Reliable Autonomous Surface Mobility (RASM). Our aim is to provide safe and reliable means for lunar rovers to travel at substantial speeds and operate in proximity to astronauts and other vehicles. Our unique partnership brings together state-of-art technologies ...

The overarching challenge of tele-presence is to provide an environment to the human operator that is sufficiently familiar that the interface itself does not become burdensome and distract from the goals of the mission. The ultimate achievement would be to embed the operator into a scene in such a way as to convince him or her that they are actually on site. We propose a technology that can poten ...

A scalable gravity offload device simulates reduced gravity for the testing of various surface system elements such as mobile robots, excavators, habitats, and deployables in a relevant environment. The device is capable of simulating reduced gravity over an arbitrary terrain including such features as slopes, obstacles, and varying surface concavity. The device consists of a linear movement sy ...

There is a continuing need within NASA for solar cells and arrays with very high specific power densities (1000-5000 kW/kg) for generating power in a new generation of ultralight space payloads. An emerging technology with promise to meet these ambitious goals are solar cells based on very thin films of discrete layers or interpenetrating networks (IPNs) of organic donors and acceptors. It is also ...
