This book introduces in detail the theory of adaptive optics and its correction technology for light wave distortion in wireless optical communication. It discusses the adaptive control algorithm of wavefront distortion, proportional+integral control algorithm and iterative control algorithm, and double fuzzy adaptive PID control algorithm. It also covers the SPGD algorithm of adaptive optics correction, deformable mirrors eigenmode method of wavefront aberration correction, vortex beam wavefront detecting wavefront aberration correction, liquid crystal spatial light modulator wavefront correction, different wavelengths of Gaussian beam transmission wavefront differences in the atmospheric turbulence and correction and with wavefront tilt correction adaptive optics wavefront aberration correction. Various distortion correction methods are verified by experiments and the experimental results are analyzed.

This book is suitable for engineering and technicalpersonnel engaged in wireless optical communication, college teachers, graduate students and senior undergraduate students.

Explores Adaptive Optics (AO) Theory and its application in optical wireless communication system Verifies various distortion correction methods by experiments for relevant theories Corrects the random wavefront distortion caused by the external environment change in real time
