ME-593N.  Laser Metrology and NDT
Fall 2000

In this course, modern laser metrology techniques are covered and their practical application to solve problems, with emphasis in nondestructive testing (NDT), are illustrated with laboratory demonstrations.  Topics covered include:
Detail examples of nondestructive testing and coherent optical metrology in solid mechanics, vibrations, heat transfer, electromagnetics, and reverse engineering are given.

Students are required to work on projects depending on their background and interests
