Paper Abstract

The phase information of the thin heated air cylinder transection was acquired with a self-collimated interferometer and line CCD camera at the frame rate of 27kHz , based on the presumption of axial symmetry ,using addition algebraic reconstruction algorithm , 2-dimension index-of-refraction distribution of the heated air in the transection was acquired ,and the 2-dimension temperature distribution was calculated, the temperature shift was observed, the central temperature of the air cylinder changed between 330K and 430K. The results show the method could be used to the measurement of near axial symmetry aero-optical medium.
