Target variation presents a challenge for Automatic Target Recognition (ATR) based on fixed models or signatures. In Phase I General Intelligence refined and applied an extension of the map-seeking circuit (MSC) architecture to recognize articulations, plausible morphs and aggregations of target models. The extended MSC architecture implements a process termed “transformational adaptivity,” ...

The measurement of cloud water content is of great importance in understanding the formation of clouds, their structure, and their radiative properties which in turn affect the climate. 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 UAVs, balloo ...

This NASA SBIR Phase II effort will develop a 1 x 10 prototype non-mechanical fiber optic switch for use with high power lasers. The proposed optical device is a fiber-based multi-channel switch to rapidly switch a fiber-coupled laser among ten output channels as an integral part of a fiber-based fixed-array laser transmitter for next-generation NASA lidar systems. The key innovation is the use ...

A program is proposed to develop a commerical source for spectral hole burning materials and their properties. The proposed program will create a file of material and their properties for this application. A crystal growth program is proposed to grow Eu:Y2Si05, Pr:YA103, and Sm:CaW04.

Several laser designers have requested Scientific Materials Corporation (SM) to consider methods to achieve a cladding for Tm:YAG diode pumped laser rods. SM has looked at several mechanical methods and concluded mechanical systems are impractical. In the early 1960's the PI of this program developed techniques to grow overlays of sapphire on ruby. These rods were used to c-w pump ruby and they wo ...
