This text provides a systematic description of the entire subject of particle field holography. Holography is used to study very small objects in a dynamic volume, providing information about the size, shape and velocity of such objects as dust, raindrops, fuel droplets and pollen. Professor Vikram aims to provide a coherent, comprehensive and self-contained treatment of the theory, practice and applications. All the necessary mathematical formulations, figures and photographs, experimental procedures and results, and literature citations are included.
