A thermoacoustic standing-wave prime mover with a quarter-wave resonator has been investigated experimentally. The working fluid is air at the barometric pressure. The holographic interferometry and hot-wire anemometry have been used. A special optical setup, based on a Michelson interferometer, has been developed and used. The setup exhibits a double sensitivity, in comparison with a common Mach-Zehnder holographic interferometer. The results have confirmed a proper function of the prime mover, and advantages of the present optical setup.
