| Abstract: | In this paper,the reconstruction precision of projection space iteration reconstruction reprojection based on beam deflection optical tomography have been studied by computer simulation with the prior knowledge of gas temperature fields.The effects of input data limited viewing angle and opaque object on the precision are discussed.As an example,the method has been used to reconstruct the arc plasma temperature fields. |
