“…In [15], the temperature, absorption, and scattering profiles were estimated by a Newton-type iteration algorithm in an absorbing, emitting, and isotropic scattering plane-parallel medium with transparent bounding surfaces. In [16], for a gray, absorbing, emitting, and nonscattering rectangular furnace surrounded by gray absorbing, emitting, and diffusely reflecting wall surfaces, the temperature distribution was reconstructed by an improved Tikhonov regularization method from a radiative energy image detected from the boundary of the furnace, while the uniform emissivity of the wall surface and the uniform absorption coefficient of the medium were updated from the temperature image grasped from the boundary. As stated in [16], the ability of this method to overcome measured errors was not good, and thus is improved in this article.…”
