ABOUT OPTICAL ENERGY TECHNOLOGIES INC OET was organized in 1984, and since then has been engaged in the manufacture of a patented, non-tracking concentrating solar collector, and the installation, and service of all types of solar energy systems. In 1997, OET was reorganized to provide expanded electro-optical, electronic, mechanical, and instrument system design and development services from concept definition, system and worst case analysis, design, fabrication, and test of electro-optical instruments and/or subsystems of larger electro-optical systems. OET has a staff of interdisciplinary senior level engineers/managers, having a cumulative experience of over 150 man-years, who have worked closely together for over 7 years. OET is currently developing, on its own funds, its patented high power, 12/1 trough concentrator for GaAs solar cells, with a "Figure of Merit" of greater than 100 watts/Kg. of panel weight ( four times that of current spacecraft solar panels ) with a unique folding configuration. OET has also developed its patented 2.8/1 pyramidal concentrator solar collector flat plate solar panel for spacecraft having a "Figure of Merit" greater than 150 watts/Kg. ( Five times that of current solar panels. ) Also in the prototype stage and flight qualified, is a patented two axis, high accuracy sun sensor for use at any orbit, with an 100 diameter field of view with different models providing readout accuracies over this field of view of 0.5 to 0.05 3s even at low earth orbit, where the earth albedo normally produces inaccuracies. This sensor uses a proprietary algorithm incorporated into the spacecraft computer to provide this accuracy and allows the optical head of this sun sensor to have a weight less than 1.4 ounces (
