Heterodyne holographic interferometry: concentration and temperature measurements in gas mixtures.
Heterodyne holographic interferometry is employed to measure refractive-index distributions in transparent media. A system using a He-Ne laser and relatively modest electronic instrumentation is described. The system was used to measure temperature and specie-concentration distribution in natural convection boundary layers in air adjacent to heated surfaces through which a second gas is emitted or injected.
