Abstract

In this paper we propose a tomographic algorithm for reconstruction of the energy profile of an optical beam from the data measured with linear bolometer. This algorithm is based on a discrete Fourier transform (DFT). When reconstructing the DFT values and making linear interpolation we used a rather in the form of concentric squares, which essentially decrease of the error of reconstruction and saved a computation time. In a computer experiment we have estimated the accuracy of the reconstruction method and determined the optimal number of projections. The proposed algorithm has been successfully used for reconstructing the beam intensity distribution from the experimental data. The result of reconstruction were compared with the data of direct measurements. It is shown that the proposed algorithm allows most fast reconstruction of spatial energy structure of an optical pulse to be done. The accuracy of reconstruction is not worse than that of the existing algorithms when the noise level is no more than 20%.
