| Research Abstract |
In measurement of distribution of gas temperature or concentration of liquid, the correct measurement is difficult, since the condition of the object to be measured is changed due to the sensor (e.g thermo couple) itself. In this study, we propose a phase tomography that is a coupling method of optical interferometer and computed tomography that is three dimensional non-destructive measurement. Experimental measurement of three dimensional gas temperature distribution agree with theoretical distribution qualitatively.
