Abstract

The shearing interferometry of holographic doublng grating byNd Y1-x A13(BO3)4(NYAB) laser to measure flow field of shook tunnel with M=4.46 is reported. The quantitative evaluation of a shearing interferogram for an axisymmetrie density field on a 15 half angle cone is performed and the result is compared with theoretical values.
