Thermometry and velocimetry in a ramjet using dual comb spectroscopy of the O 2 A-band

Dual comb spectroscopy (DCS) of near-infrared H O absorption has been demonstrated in the past for low-uncertainty flow measurements in ground test ramjets. However, H O is scarce at actual ramjet flight altitudes, so oxygen is a preferable absorption target. Here, we demonstrate DCS of the O A-band...
