Abstract

In this project the vibrational behavior of a circular cured carbon fiber plate and a tennis racket is examined using a speckle-pattern interferometry system built and designed by students at Illinois Wesleyan University. Specifically, the mode shapes and mode frequencies are presented and discussed. With regards to the carbon fiber plate, the effects of the orthogonal construction of the plate on the vibrational behavior are studied. With regards to the tennis racket, the mode shapes of the racket are imaged for the first time using speckle-pattern interferometry. Furthermore, the effects of commercially available vibration dampers on the vibrational behavior of a tennis racket is also presented. In addition, the challenges of imaging various objects using speckle-pattern interferometry are explained, along with several methods for overcoming these challenges.
