Thermocouple measurements and TSI calibration. (a) k-factor determined by the linear regression of thermocouple and TSI acquisitions using k = 1. TSI temperature evaluation compared with thermocouple estimation when varying (b) the spatial-peak-temporal average acoustic intensity (Ispta) and (c) the total energy (E) of the pulse.
