A versatile integrating sphere based photoacoustic sensor for trace gas monitoring
Mikael Lassen, David Balslev-Clausen, Anders Brusch +1
A compact versatile photoacoustic (PA) sensor for trace gas detection is reported. The sensor is based on an integrating sphere as the PA absorption cell with an organ pipe tube at…
