Devdas Shetty, professor of mechanical engineering, and Jonathan Hill, associate professor of electrical and computer engineering, CETA, are coauthors of a paper, "Optical Instrumentation for Vibration Measurement and Monitoring," along with Ahad Ali of Lawrence Technological University in Michigan.
The article describes a system the authors developed that indirectly measures vibration by using a position-sensing device to measure a laser beam reflected from the device being measured. The system was developed for use with machine cutting tools and can be used to monitor the performance and wear of such devices. The article appeared in the June 2011 issue of the International Journal of Precision Engineering and Manufacturing, a well-known publication of the Korean Society for Precision Engineering.
