Abstract
In the present paper, application of Talbot interferometry for real-time vi bration measurement is investigated. Experiments were conducted to measure/ monitor out-of-plane motion of a vibrating loudspeaker membrane. Experiment al results demonstrate that by using Talbot interferometry out-of-plane vib rations as well as phase lag between driving force and membrane oscillation can be measured.
