Abstract

A Mach Zehnder interferometer has been constructed with each arm affixed to opposite sides of a vertically cantilevered test beam. Static deflection and tip velocity have been detected by processing and counting the fringes at the output. Tip velocity signal is used in a closed loop control scheme to dampen vibrations.
