Abstract
Mode shape measurement is pivotal to the success of any piezoelectric and non-piezoelectric resonator design. This paper describes an improved laser-speckle mode shape visualization system for measuring speckle images simultaneously generated on device surfaces using a red and a violet semiconductor lasers.
