The optical computerized tomography (OCT) of incomplete data for three-dimensional detection of complex flow field is urgent to be but still not be resolved. A new three-dimensional tomography with the fusion of virtual and real experiments is proposed, which combines the technology computational fluid dynamics (CFD), computational flow imaging (CFI), and OCT. The experimental results of double-peak temperature field indicate that, compared with the reconstructed results of full data, the error of unsymmetrical the double-peak reconstructed by the three-dimensional tomography with fusion of virtual and real experiments is less than 5%. So this new three-dimensional tomography can reconstruct the flow field of incomplete data satisfactorily, improve the reconstruction resolution greatly, and thus provides a brand-new way for the incomplete data reconstruction with limited viewing angle.
