Abstract

This chapter considers coherent effects that accompany the propagation of laser radiation in tissues and the interaction of laser radiation with cell flows. These effects include diffraction, formation of speckle structures, interference of speckle fields, and scattering frommoving particles. Principles of quasi-elastic light scattering (QELS) spectroscopy, diffusion wave spectroscopy (DWS), full-field speckle imaging (LASCA), confocal microscopy, OCT, digital holographic and interferential microscopy, SHG imaging, and nonlinear Raman scattering microscopy are discussed.
