This NASA Small Business Innovative Research Phase II project will develop a compact, low-cost, wavelength locked seed laser for injection locking high powered Nd:YAG lasers used in a range of lidar remote sensing applications including molecular profiling of the atmosphere. Precise wavelength control of the seed laser will be achieved by actively locking the laser wavelength to an absorption li ...

The proposed optical device is a fiber-based multi-channel switch to quickly switch a fiber-coupled laser among many possible output channels to create a fiber-based fixed-array laser transmitter for next-generation NASA lidar systems. The key innovation is the use of an arrangement of electro-optic prisms created in a nonlinear optical crystal through domain reversal to direct the laser into one ...

Resodyn Technologies proposes a new technology that enables the application of polyimide based cryogenic insulation with low hydrogen permeability. This effort supports the Vision for U.S. Space Exploration policy and the Exploration Systems Enterprise. This technology will benefit designers of cryogenic fuel tanks envisioned for new Earth-to-Orbit (ETO) Transportation vehicles. Specifically th ...

Automated detection of land cover changes between multitemporal images (i.e., images captured at different times) has long been a goal of the remote sensing discipline. Most technology in this area has focused on methods for detecting and identifying land cover or surface object changes in two or more images, but precise co-registration of images remains a key challenge. In fact, image-to-image r ...

The water content of clouds, whether in liquid or ice form, is a key variable to be measured when either calibrating remote sensing systems or when calculating the climatological effects of clouds. While a variety of sensors exist for making these measurements, all of the existing sensors require far too much power or other energy input to be used on small platforms with limited payloads such as ...
