• 1. USING SOUND TO MEASURE TEMPERATURE

  » ABSTRACT A method to measure the real time temperature distribution along an interferometer path based on the propagation of acoustic waves is presented. It exploits the high sensitivity of the speed of sound in air to the air temperature. In particular, it takes advantage of a special set up where the generation of the acoustic waves is synchronous with the amplitude modulation of a laser source....Continue Reading »
