Abstract

In Optical Computerized Tomography (OCT) reconstruction, the well-known restrictions are positivity of the field and boundary conditions. In this paper, the extra information --the probed value of a set of isolated points, which are readily available in the industrial practice, is introduced into OCT based on information fusing techniques. To solve the incompatibility of the different testing systems, which brings high frequencies disturbance to the reconstruction, an adaptive algorithm is developed to make a good use of the pointwise priori. The algorithm, derived from the third Algebraic Reconstruction Technique (ART3), is not only friendly to the information from various measuring systems, but very robust to irregular noise and even missing projections as well. By analyzing the simulated experiments, we strongly suggest that OCT give some attention to the information from external resources.
