Numerical simulation and experiment of optothermal response of b...

A finite element method computation model for analyzing optothermal interaction of polychromatic light and biology tissue is proposed and proven by experiment. A continuous xenon lamp is employed as an example. First, the spectral energy distribution of the xenon lamp is measured and found to be equivalent to a series of quasi-chromatic light with different central wavelengths, different energies, and certain bandwidth. Next, according to the reported thermal and optical parameters of porcine sk
