摘要
以半导体激光器为光源、利用正交双频光栅（ＯＤＦＧ）ＣＣＤ系统剪切干涉对带平板边界的半圆柱体热源的二维温度场进行实时诊断，分析剪切干涉图时，用柱函数系作为拟合基底，给出二维自然对流温度场的定量分布。
The real time testing of the 2 D temperature field which is produced by a semi column heat source with a plane boundary is carried out by using the shearing interferometry with the orthogonal double frequency gratings and the semi conductor laser.The curve fitting based on the cylindrical functions is used to analyse the interferogram.As a result,the distribution of the two dimension temperature field in the natural convection is given.
