Photoacoustic Cell Signal Processing

Document Thumbnail

A photoacoustic cell is used to measure the absorptance of gases at infrared wavelengths. A pressure pulse is created when the gas absorbs a light pulse, exciting resonances within the cell. A microphone provides the cell's output signal whose energy is (ideally) proportional to the absorbed light energy. The paper describes a novel approach for processing the cell's noisy output.
