Improving space laser communication using adaptive optics system based on MEMS technology

Since a free space optics communication system cannot be free of atmosphere turbulence by nature, a micro-Adaptive Optics system based on Micro-Electro-Mechanical Systems technology is discussed, which meets the volume, weight, power consumption, price and heating/cooling requirements in this case. It not only compensates atmospheric turbulence, but also decreases the wavefront aberration resulted by random gravity, heat and component surface error during manufacturing to some degree. The laboratory experiments are also presented to reveal the benefit that such system can provide. Future possible improvements are addressed as well.
