Abstract：

Tunable　Diode　Laser　Absorption　Spectroscopy　(TDLAS)　technology　and　Computed　Tomography　(CT)　technology　were　combined　to　reconstruct　two-dimensional　temperature　distribution　of　bunsen　burner　flame　through　getting　the　most　fitting　spectrum.　Zeromean　Normalization　Cross　Correlation　(ZNCC)　value　and　Sum　of　Squared　Difference　(SSD)　value　were　used　as　target　to　analyze　accuracy　of　32-path　reconstruct　temperature　distribution.　And　ZNCC　value　comes　to　0.994,　SSD　value　comes　to　0.000　86.　32-path　CT-TDLAS　system　was　designed　and　applied　to　measure　the　two-dimensional　temperature　distribution　of　Bunsen　burner　flame,　and　compared　with　the　results　of　thermocouple.　The　results　show　that　the　temperature　distribution　trends　between　thermocouple　and　TDLAS　are　same　while　CT-TDLAS　has　higher　precision　and　resolution.　The　feasibility　and　accuracy　of　reconstruction　using　tunable　diode　laser　absorption　spectroscopy　technology　and　computed　tomography　technology　is　demonstrated.　©　2019,　Science　Press.　All　right　reserved.
