Iteration compensation of inside fringe in reconstructing field with an opaque object
- 14 Downloads
An algorithm is suggested to compensate the inside fringe in reconstruction field for the iterative distortion when an opaque object exists. With numerical simulation, a model field with an opaque object is reconstructed by a new algebraic reconstructing technique (ART), named Simple Self-correlative ART (SSART), which shows that the inside fringe of the reconstructed field is quite irregular with serious profile distortion. An algorithm of the compensation of the inside fringe for the iterative distortion is suggested and applied to the reconstruction of the field. It is found that the reconstructed field is quite similar to the model. With the compensation algorithm, the field with an opaque object in can be accurately reconstructed by SSART.
