Chirp-modulated light-induced thermoelastic spectroscopy for simultaneous precise measurement of resonant frequency and gas concentration

This paper demonstrates chirp-modulated light-induced thermoelastic spectroscopy (LITES), enabling simultaneous precise measurement of quartz tuning fork (QTF) resonant frequency and gas concentration. The injection current of the laser is modulated using the chirped signal. The chirped laser beam i...
