| Title: Photoacoustic Detection Technology | |
| Abstract: Due to their overwhelming advantages over traditional electro-acoustic sensors, optical acoustic sensors have attracted great attention in many fields. This paper introduces the latest research achievements of our research group in weak sound signal detection technology. Diaphragm based Fabry-Perot acoustic sensors and cantilever beam based photoacoustic sensors,including gold,aluminum, titanium,graphene and MEMS based silicon nitride membranes, will be introduced. High precision acoustic signal detection technology and sensitivity enhancement technology based on phase demodulation will be emphatically introduced，including ellipse fitting, line fitting and other techniques. | |
