Abstract
A Michelson-type visible spatial interferometric method is used to measure very high speed vibrations of a bassreflex loudspeaker, and further its resonant frequency. The goal of investigation is to create the model for measurement of nonelectric, low-amplitude, high-speed alternating physical quantities. The contribution of this paper is this new application area.
