Photoacoustic technology is an innovative spectrum analysis method, which is different to traditional infra-red technology. This method transfer effective spectrum into acoustic signal, and assemble this acoustic signal through high sensitive microphone, with this signal the gas concentration will be calculated.
Because of special optics construction, acoustic signal assemble method and precise signal calculated process, photoacoustic technology became an effective way to assemble weak opto-acoustic signal and prevent background signal interference. It is an innovated technology special suitable for trace gas concentration measurement in complicated situation.
