(a, b) Fluence and temperature increase measured by the photodetector and thermocouple in the in vitro phantom experiment. (c) The photoacoustic signal intensity increased with the different temperature of the heating tunnel (*, p < 0.05). Note that the temperature of the water bath was almost unchanged due to the special setting of the phantom and an optical absorber (hair) (N = 3 in each experiment). (d) The temperature change of the hair during experiment.
