Photographic acoustic
WebDec 15, 2024 · Photoacoustics is the study of vibrations induced in matter by light. Laser light causes localised heating when it is absorbed by a surface. This in turn makes the … Webthe gas (an acoustic signal) in the closed cell. 5. Two microphones mounted in the cell wall measure this acoustic signal, which is directly proportional to the concentration of the moni tored gas present in the cell. 6. The filter wheel turns so that light is transmit-ted through the next optical filter, and the new signal is measured.
