Abstract: By using the Tikhonov Regularization Method,the related techniques for the numerical inversion of black body radiation are discussed.The special interest focuses on the presentation and experiment of some new and hybrid algorithms,which generate a good starting-up strategy separately with Newton method and a 3-order-convergence iterative scheme of solving the Morozov discrepancy equation to determine the regularization parameter.The numerical test is also made to illustrate the high efficiency and good stability of the proposed algorithms.
