Features: This book primarily discusses the phenomena and laws arising from the propagation of light waves in random media. It provides a detailed introduction to the fundamental theories of light wave propagation in random media, as well as the latest research achievements and current research frontiers in this field over the past decade by scholars both domestically and internationally. The content includes:
Basic concepts of random fields, including single-lens diffraction of random fields and the diffraction of plane waves through random diffraction screens;
Single scattering theory of light waves propagating in weakly scattering media;
Theoretical foundations of light wave propagation in continuous media, including the parabolic equation approximation, perturbation theory, Markov approximation, mean field, second-order coherence function, fourth-order coherence function, and intensity fluctuations;
Radiative transfer equations and diffusion theory involved in the propagation of light waves in scattering biological media;
Recent research achievements on the effects of turbulence on light wave propagation, such as atmospheric scintillation, arrival angle fluctuations, aperture smoothing by Andrews theory, phase intermittency, and enhanced backward scattering by turbulence;
Improvement and enhancement of image quality when light waves pass through the same random medium twice;
Propagation and imaging laws of light waves in biological media discussed from the perspectives of light scattering, photon migration, and photon absorption.
The primary readers of this book are researchers and engineering technicians in fields such as radio communication, atmospheric optics, laser technology, laser medicine, biomedical engineering, optoelectronic guidance, and lidar. It can also serve as a textbook for graduate students in related disciplines.
