LIDAR OUTGOING LASER ENERGY MEASUREMENT SYSTEMReagan, John; Gibbons, Jasper; Moss, David; University of Arizona (International Foundation for Telemetering, 2004-10)A flexible system has been designed to accurately measure and average the outgoing laser energy of a micro-pulse LIDAR unit (MPL). This system incorporates specifically designed analog measurement circuitry interfaced with a microcontroller, allowing researchers to manage experiments from a personal computer. The final system produces a linearly proportional response between an incident laser energy input and the analog and digital circuitry’s output, accurate to within 0.1%. Custom designed algorithms allow the system to average the energy measured in a series of pulses. Each series can range on the order of tens of thousands of pulses.
