Improvement of The Reconstruction Algorithm of Optical Computerized Tomography
Optical computerized tomography (OCT) has found wide applications in the noncontact detection of the flow field such as temperature filed, density field etc. However, the reconstruction of OCT is a projection reconstruction of incomplete data, and the algebra reconstruction technique usually adopted cannot solve the problem of reconstruction precision very well. A new kind of algebra reconstruction technique is presented. The property matrix including the prior knowledge is introduced. The fixed ultra-relaxation coefficient usually determined artificially is abandoned and an unfixed ultra-relaxation coefficient is adopted in the algorithm. The reconstruction results indicate that the algorithm with property matrix and unfixed ultra-relaxation coefficient can reconstruct the flow field of incomplete data satisfactorily, improve the reconstruction precision greatly, and match the measured results.
