FPGA-based adaptive optical system for atmospheric applications

Many atmospheric applications based on the laser beam passed through the Earth’s atmosphere are exposed the distortion of the laser beam wavefront, which ultimately leads to a decrease in their efficiency. Such tasks include the transmission of powerful laser radiation over a distance (recharging batteries of drones and low-orbit satellites, delivering energy to hard-to-reach places, destroying fragments of space debris in low orbits), creating protected optical communication lines, increasing the resolution of telescopes, etc. One of the methods to improve the efficiency of such systems is the use of adaptive optics methods and tools that allow the wavefront correction in real time. The features of constructing such a system using FPGA as the main control element are considered.
