CT-TDLAS-I is a revolutionary measurement system which can detect time-series 2D temperature and concen-tration distributions in combustion, reaction and flow fields. It utilizes the CT-TDI AS(Computed Tomogra-phy-Tunable Diode Laser Absorption Spectroscopy) technology developed by Tokushima University and it can be applied to engines(in-cylinder and exhausts), burners,boilers, gas turbines for timc-series 2D temperature and concentration measurement. Multi-path laser beams are introduced to the measurement area and 2D temperature and concentration distributions are reconstructed by CT using multi-path absorption spectra.
