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.
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 to be discussed in this course:
Light basics (nature of light, wave theory of light, reflection, refraction, diffraction, coherency, interference, geometric optics) Optical stress measurement using photoelecticity Laser technology Optical displacement measurements using moire and Michelson interferometry Deformation measurement using digital image correlation*
