摘要: <正>1 引言 激光全息干涉技术是进行三维流场实验研究的重要手段之一.三维流场的全息层析,实际上就是在同时获得三维流场多方向干涉图的基础上,把三维流场分成一组平行的截面,根据多方位的干涉数据,由计算机分别对不同的截面重建三维流场的参量分布.由于这一方法

Abstract: A simple holographic interferometric system is designed. The interferograms of thermal diffusion in air are processed and measured by means of a computer image analyzing and processing system. The temperature distributions of two sections in the air flow are reconstructed and compared with thermal couple measurements at three points.
