Abstract:In this paper, the reconstruction precision of Fast Fourier Transform Iteration has been studied by computer simulation with the priori knowledge of refractive index fields. The effects of increased input data error and limited total viewing angle on the precision are discussed. As an example, it has been used to reconstruct the flame temper ture fields, and the results are compared with thermocouple measurem -ents.
Keywords:image reconstruction  interferometrio holography  tomography
