摘要
A method for studying vibrational modes of an electro-acoustic device includes driving the electro-acoustic device to produce at least one vibrational mode therein, collecting phase and amplitude data from the electro-acoustic device using optical interferometry, and mapping the at least one vibrational mode based upon the collected phase and amplitude data. The phase and amplitude data may be processed to provide an instantaneous three-dimensional view of the at least one vibrational mode. Furthermore, a sequence of instantaneous three-dimensional views may be constructed to form a motion picture of the at least one vibrational mode. Additionally, collecting may include raster scanning to provide phase and amplitude data across a surface of the electro-acoustic device.
