Speckle photography is an advanced experimental technique used for quantitatve determination of density, velocity and temperature fields in gas, liquid, and plasma flows. This book presents the most important equations for the diffraction theory of speckle formation and the statistical properties of speckle fields. It also describes experimental set-ups and the equipment needed to implement these methods. Speckle photography methods for automatic data acquisition and processing are considered and examples for their use are given.
