Applications of Holography and Optical Data Processing

Applications of Holography and Optical Data Processing contains the proceedings of the International Conference on Applications of Holography and Optical Data Processing, held in Jerusalem in August 1976. The conference is attended by eminent scientists in the field of optics, characterized by high-level scientific presentations and discussions.
The collection is a representation of research on the cutting edge of applied and theoretical optics. The four-day meeting covers topics on holographic applications in medicine, interferometry, display, storage, and retrieval, as well as image processing, measuring techniques, spectroscopy, and recording materials and devices. The participants of the conference believe in the promising future of research on Optical Data Processing as long as techniques are complemented by electronic support.
The book will be of value to electronics engineers, technicians, computer scientists, and computer engineers.
