Reconstruction of 3-D refractive index fields by an improved Conjugate-gradient iterative method
The reconstruction precision of an improved Conjugate-gradient iterative method, the effects of increased input data error and limited total viewing angle have been studied based on the knowledge of refractive index fields aid of computer simulations. As an example, the flame temperature fields were reconstructed, and the results are compared with thermocouple measurements.
