Method of remotely characterizing thermal properties of a sample [PDF]
, 1992 A sample in a wind tunnel is radiated from a thermal energy source outside of the wind tunnel. A thermal imager system, also located outside of the wind tunnel, reads surface radiations from the sample as a function of time.
