Measurement of temperaturę field around a single steady vapor bubble using phase shift interferometry

In the current paper, the local temperature around a single axial symmetric vapor bubble is measured using the phase shift interferometry. For this purpose the four frames technique, Itoh algorithm for phase unwrapping and Abe inversion for computing the local temperature from the mean one were used. For generating a single vapor bubble a special test cell was constructed. With this technique a high-resolution spatial temperature distribution has been determined.
