Overview

This is the first book to provide a thorough and systematic description of the entire subject of particle field holography. The use of holography to study very small objects in a dynamic volume is a technique of importance for scientists and engineers across a variety of disciplines for obtaining information about the size, shape and velocity of small objects, such as dust particles, fuel droplets, raindrops, pollen, and bubbles. Professor Vikram has made major contributions to the field, and here provides a coherent, comprehensive and self-contained treatment of the theory, practice and applications. The volume is written to satisfy the needs of researchers in the technique, practicing engineers dealing with applications, and advanced students in science or engineering departments. All the necessary mathematical formulations, figures and photographs, experimental procedures and results, and literature citations are therefore included.
