Fig. 5From: Study of a periodic spectral fluctuation existing in a fibered optical feedback cavity-enhanced absorption spectroscopy (OF-CEAS)The feedback light signal (black) and the simulation results (red). The simulation results includes the interference effect calculated using the Formula (3) and simulation of the absorptions based on HITRAN 2012 (P = 1.0 atm, T = 25 °C)Back to article page
