Abstract
An apparatus for in-situ calibration of a photoacoustic sensor is provided. The apparatus includes a light emitter to emit light along a transmission path to a gas and an acoustic sensor element configured to detect an acoustic signal emitted from the gas based on the received light. Furthermore, the apparatus includes a sensing unit configured to detect the light transmitted along the transmission path and to provide an output signal, and a calibration unit to receive the output signal from the sensing unit and to provide a calibration information based on the output signal received from the sensing unit.
