Instructor Class Description

Time Schedule:

Wei-Chih Wang
M E 557
Seattle Campus

Experimental Stress Analysis II

Theory and practice of optical mechanics, including interferometric techniques (moire and holographic), geometric moir methods, and photoelasticity. Lecture and laboratory. Prerequisite: graduate standing or permission of instructor. Offered: W, even years.

Class description

The main goal of this course is to introduce students to the characteristics of light which can be used to accomplish a variety of engineering tasks especially in mechanical analysis. At the end of the course, students should be familiar with the range of possible applications for optics in mechanical measurements such as strain, stress, and deformation analysis.

Topics will be discussed in this course are:

Review of Optics and Electromagnetic wave Theory Optical measurement tools: Light sources and photodetectors Geometric Moiré: In-plane displacement measurement Geometric Moiré: out of plane displacement measurement Moire Interferometry: Interference and Diffraction, Grating fabrication Moiré Interferometry: Holographic and Laser Speckle Interferometry Photoelasticity: theory, techniques and Introduction to fiber optic and waveguide delivery and detection
