Introduction

Jon Blotter has focused research in structural dynamics, acoustics, and laser / optical based measurement techniques. In the structural dynamics and acoustics area, the BYU Acoustics Group has several projects ranging from improving the acoustics at the LDS Conference Center in Salt Lake City to the development of an energy density sensor to be used by NASA on launch pad test facilities. BYU has exceptional facilities consisting of anechoic and reverberant chambers, computer modeling software, and test equipment. The BYU Acoustics Group consists of 3 faculty, 10 graduate students, and approximately 8 undergraduates in Physics and Mechanical Engineering. Besides project group meetings, the entire Acoustics Group meets on a weekly basis for research updates, lectures, seminars from invited speakers, and tours. Recent work in the area of optical based measurements has focused on small displacement measurement methods. Projects have included the development of a fringe control technique based on diode laser current modulation, an improved calibration process for an optical based displacement measurement technique known as Projection Moire Interferometry, development of in-plane displacement measurement capabilities, the development of fiber optic based systems, and the extension of some current methods to measure displacements on micro-structures. Other laser based measurements of interest include whole field heat flux and temperature measurements. The development of these measurement techniques has been supported by industry and research laboratories.
