Abstract

According to the direct exposure from the flash radiographic image,the direct method for inverse Boltzmann transport equation is presented.The line absorption coefficients and interface locations of object are reconstructed directly at the same time.The algorithm uses ART,Tikhonov,TSVD and TV regularization methods because of the ill-posedness of inverse problems.Numerical results with appropriate regularization parameter agree well with the reference value and avoid amplifying the scatter noise.
