The thermometric capability of a two-line fluorescence technique using iodine
seed molecules in air is investigated analytically and verified experimentally
in a known steady compressible flow field. Temperatures ranging from 165 to 295
K were measured in the flow field using two iodine transitions accessed with a
30-GHz dye-laser scan near 543 nm. The effect of pressure broadening on
temperature measurement is evaluated.
