Laser-induced photoacoustic signal phase was employed for measurements of optothermal parameters of pig abdomen stratum corneum and epidermis. The non-radiative relaxation time was found to be 28 ms and the thermal diffusion time was 370 ms, yielding a thermal diffusivity value of (4.1 +/- 0.8) x 10(-4) cm2 s-1. This value compares well with other literature values for skin obtained using photothermal techniques.
激光诱导的光声信号相位被用于测量猪腹部角质层和表皮的光热参数。发现非辐射弛豫时间为28毫秒，热扩散时间为370毫秒，得出热扩散率值为(4.1±0.8)×10(-4)平方厘米每秒。该值与使用光热技术获得的其他皮肤文献值相当。
