Most spatial information perceived by living creatures and machines is conveyed by wave propagation, which intrinsically carries a phase component. Even so, machine sensing typically relies exclusively on intensity while entirely ignoring phase relationships. Holography constitutes a method of preserving phase relationships by recording a snapshot of the intensity profile of controlled interference patterns. By so doing, an additional third dimension—depth—is recovered from two-dimensional sampling. This course will demystify holographic interference patterns by showing how to gather and interpret them and recover depth information. Course topics will step through principles enabling you to conceptually appreciate holographic phenomena and understand constraints faced by recording system designers. Then, using sound waves instead of laser light, participants will have an opportunity to compete in teams to develop a real-world measurement system and computationally recover a scene. Measurement devices and MATLAB starter code will be provided. \\\*Work sponsored by the Department of the Air Force under Contract #FA8721-05-C-0002.
