摘要: Linear regularization has been applied to the HL-2A infrared imaging bolometer reconstruct local plasma emission with one-dimensional (1D) and three-dimensional (3D) modeling under assumption of toroidal symmetry. In 3D modeling, a new method calculate detector point response function is introduced. This can be adapted an arbitrarily shaped pinhole. With full treatment geometry, up 50% mean-squared error reduced compared 1D modeling. attributed effects finite size being taken into account in Meanwhile, number pixels optimized 20 × by making trade-off between sensitivity system. The radiated power density distributions have calculated as demonstration using respectively.
