Title: Holographic real-time imaging of standing waves in gases.
Authors: Peterson, Richard W., Pankratz, Stephan J., Perkins, Trent A., Dickson, Adam, Hoyt, Chad
Source: American Journal of Physics. Sep96, Vol. 64 Issue 9, p1139. 4p. 8 Diagrams.
Subjects: Holographic interferometry, Sound waves, Interferometers -- Design & construction, Physics
Abstract: Discusses the development of stroboscopic holographic interferometry at an advanced undergraduate level allowing real-time imaging of standing sound waves in gas filled, closed tube resonators. The building of a heterodyne Mach-Zehnder interferometer to show the feasibility of interferometric detection of sound waves in a small cell; How the laser irradiance is modulated; Observations of fractional fringe shifts and sound reflections.
