Book excerpt: Experienced and novice holographers receive a solid foundation in the theory and practice of holography, the next generation of imaging technology, in this superb text. The book's `how to' aspects enable readers to learn hologram acquisition at the microscope and processing of holograms at the computer as well as digital imaging techniques. A complete bibliography on electron holography and applications of the method to problems in materials science, physics and the life sciences round out the volume's coverage.
