Gas-Liquid separation is an acute microgravity problem. Existing devices use centrifugal motion on microporous membranes to separate the two phases. Centrifugal devices consume electricity and are prone to failure. The microporous membranes easily foul and have significant water loss. Novel membrane devices are proposed. Membranes can simultaneously disengage gases from gas-liquid dispersion and d ...

Vertical cavity surface emitting lasers (VCSELs) is a new technology which can be used for developing high performance laser components for atom-based sensors technology. The narrow linewidth of VCSEL emission combined with good polarization extinction ratio and large spacing between the longitudinal modes, which makes them relatively immune to mode hopping, and their high reliability make them un ...

Small satellites such as CubeSats are in need of responsive propulsion, but are limited due to their size. Though single pulse, AP/HTPB fueled solid rocket motors exist in the market, greater mission flexibility is to be had from a motor with the capability of a second ignition in the same volume constraints. Digital Solid State Propulsion (DSSP) proposes research into the technology to not only t ...

An automated in-space recycling system for 3D printer feedstock will provide game-changing resupply benefits including but not limited to launch mass reduction, mission reliability increases, and decreased reliance on resupply from Earth. To bring these benefits to ISS in the near term, Made In Space proposes the further development of their unique recycling system, called R3DO, for transforming ...

NASA needs high stability laser source of 1W output power for Lidar applications. Princeton Optronics has developed ultra-stable, narrow linewidth diode pumped solid state lasers using stable packaging and high performance locker. We have also developed high power Vertical Cavity Surface Emitting Laser (VCSEL) semiconductor laser sources. We propose to develop a high reliability master oscillator ...

Princeton Optronics proposes to develop a high energy pulsed laser source based on a novel approach. The approach consists of a technique to combine a large number of diode pumped solid state lasers. The resulting laser can be packaged in a very small package. We will develop the laser and package it into a laser welded package which can be space qualified. We can achieve 50mJ or higher level of e ...

Leveraging on recent breakthroughs in broadband photonic devices and components for RF and microwave applications, SML proposes a new type of broadband microwave spectrometer with performance and affordability that were not attainable before. The photonic microwave spectrometer overcomes the constrains associated with microwave electronics, linearly and simultaneously offering 6-18 GHz (potential ...

Cities must perform detailed assessments of sidewalks and streets, including curb ramps, pedestrian signals, crosswalks, street furniture, and other components to determine compliance with the Public Rights-of-Way Accessibility Guidelines. However, current assessment methods are inadequate or unreasonable due to time and resources required. The objectives of this project are to: 1) develop elect ...

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 ...
