ME-593
/ ME-5304. Laser Metrology and Optical NDT
Term C’2024
In this course, modern laser metrology techniques are discussed and their practical applications to solve problems, with emphasis on nondestructive testing (NDT), are illustrated with laboratory demonstrations. Topics covered include wave and Fourier optics, classic and holographic interferometry, speckle techniques, solid-state lasers, fiber optics, CCD cameras, computer vision, camera calibration methods, and image processing and data reduction algorithms as required in quantitative fringe analysis. 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.
Recommended background: mechanics, materials, physics, and knowledge of a high-level computer programming language.

CLASS
STRUCTURE
Class will involve a variety of settings including lecture, small and large group discussions, and laboratory demonstrations. You are expected to come to every class prepared for an in-depth discussion of the topics listed on the schedule. You must have completed the relevant readings before coming to class! Reading assignments will be announced in advanced and are based on textbooks and handouts. Because a great deal of the value gained from this course will revolve around in-class activities, active attendance and participation during all class periods is expected.
GRADING
The grade for the course will be based: 25% on homework
25% on midterm exam
50% on project and class discussions
Homework is due by 1:00 PM on the due date unless otherwise noted. No late homework will be accepted.
