Observation of surface vibration modes by stroboscopic hologram interferometry


Play all audios:

ABSTRACT Powell and Stetson1 have shown that holography can be used to study the vibration modes of a surface. The technique they employed was to record a hologram while the surface was


actually vibrating. The reconstructed image from such a hologram varies in brightness with the total excursion of the surface movement, and gives a kind of “time-averaged” contour map of the


vibration amplitude. We wish to report a method of real-time analysis of the surface shape and to demonstrate its advantages. Access through your institution Buy or subscribe This is a
