Abstract
"Coherent Technologies Inc. (CTI) proposes to develop a laser communication system (LCS) coupled with a high-speed pointing and tracking scheme for greater than 100 Mb/s data rate, for optimal conditions, and 64kbits/sec, for poor atmospheric conditions,applications for long range (>50km) optical communications. The LCS will provide eyesafe operation with an engagement range greater than 50 km among moving aerial vehicles (including VTUAVs) and ships. The dual mode AMCW and pulsed (high peak power), highrepetition rate laser transmitter optimally coupled to a compact pointing and tracking unit will be designed to reduce the probability of data link breakdown due to low visibility conditions (i.e. fog). The approach will capitalize upon innovativetransceiver and scanner designs developed by CTI for laser radar systems and the advancing scanner technologies such as Micro-Opto-Electrical-Mechanical Systems. The baseline architecture uses a mid/near transmitter optimally coupled to micro-mirrorassembly. Three potential configurations for tracking in a highly dynamic environment are envisaged. The Phase I effort will generate system level signal-to-noise ratio assessments for data link performance under various environmental conditions, (2)establish closed-loop pointing and tracking scheme for maximum link performance, and (3) develop a proof-of-principle prototype and execute risk reduction measurements to ensure technical and cost feasi
