Holographic Techniques
for Advanced Photonic Systems

Overview

• This short course provides a working knowledge of current techniques in holography that provide new capabilities for medical imaging, optical data storage, and optical communications. Topics covered include: the basic principles of analog and digital holographic recording processes, image analysis techniques, coupled wave analysis, an overview of new photopolymer recording materials for analog recording, characteristics of digital cameras for digital hologram recording, and applications to medical imaging in biological tissue samples, spectral/spatial imaging, optical data storage, and filters for wavelength division multiplexing and code division multiple access communications.

Intended Audience

• Engineers, scientists and managers who want to develop an understanding of holographic techniques and their application in modern photonic systems.
