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.

The book gives a detailed description of optical wireless communication (OWC), including optical laser communication, visible light communication, ultraviolet communication, underwater optical communication and future communication technologies. To achieve an integration between theory and practice, the book avoids tedious mathematical deductions and includes theoretical materials as exercises. Most of the exercises are originated from published journal articles. These exercises will aid the readers in understanding the basic concept and methods and evaluating their knowledge acquisition in the field of OWC. The book is structured into Ten chapters that covers main aspects of OWC:- Optical wireless communication system- Coherent optical communication- Modulation, demodulation, and coding- Atmospheric channel, channel estimation, and channel equalization- White LED communication- Underwater laser communication- Ultraviolet communication- Acquisition, aiming, and tracking technology- Partially coherent optical transmission- Optical communication in the futureThe book is a suitable reference for undergraduate or postgraduate students majored in communication engineering, electronic information engineering or computer science, as well as the engineers and technicians in related fields.

This book introduces the theory and research methods of partially coherent optical, points out the significance of this study, analyzes the basic theories involved in partially coherent light, and explains the complete coherence of laser is not a necessary condition for good directivity, and partially spatially coherent optical sources can also produce the same far-field intensity distribution as lasers. This type of beam with good directivity but only partial spatial coherence is called a Gaussian Schell model beam, which can be used as a physical model to describe multimode lasers under certain conditions. This book is applicable to the large number of engineers and technicians involved in wireless optical communication and college teachers. It can also be used as a teaching material for graduate students and senior undergraduates in related fields.
