High-sensitivity all-optical PA spectrometer based on fast swept laser interferometry
A high-sensitivity all-optical photoacoustic spectroscopy based on fast swept laser interferometry is proposed to trace gas detection. The momentary cavity length of the fiber-optic Fabry–Perot microphone is demodulated by a fast swept-laser interferometry with an instantaneous frequency demodulatio...
