流场显示中的NYAB激光动态剪切干涉术
Dynamic shearing interferometry with NYAB laser in flow visualization
【摘要】 本文报道把微型的NYAB(硼酸钕钇铝)自倍频激光器用于风洞流场动态剪切干涉测量的工作。
【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.
