Photoacoustic setup

The photoacoustic technique is a method to extract thermal properties from thin film and bulk samples.  The technique involves periodic laser heating and indirect probing of sample temperature through sensing the pressure change generated in an enclosed volume of gas above the sample surface.PHOTOACOUSTIC
