T-ray PT prototype based on analysis of the T-ray’s merits was proposed and an NIR PT simulation system was developed in this paper. The architecture, algorithm and characteristics of the simulation system were studied through experimental test. Evaluations of the simulation system performance and corresponding promotional approach were made. It was shown that the solution of simulation system could be adapted for THz PT technology, and that the experimental results proved that the simulation system itself is suitable for parameter measurement of two-phase flow.展开更多
