Measurement of Transient Density Distribution by Mach-Zehnder Interferogram

Abstract

In order to measure the transient density distribution of gas jet flow, automatic and high reliability system has been developed. The VTR images of Mach-Zehnder interferogram are automatically analyzed by the Engineering Work Station, resulting in the two-dimensional transient density distribution to be obtained. The calculated density distributions were compared with the data obtained by the probe type density meter, showing high accuracy.
