| 摘 要： | 本文对轴对称位相物体的全息干涉计量中光线在位相物体中的折射引起的计量误差进行了计算分析,并且介绍了一种修正这种误差的简单方法。根据这一原理对酒精灯火焰和氢气火焰的温度分布进行了全息干涉计量。在干涉条纹的细化搜索中,采用了计算机图像处理方法。

| Abstract: | The Double-exposure holographic interferometry is applied to measuring the temperature profiles of axisymmetric spirit-lamp flame and hydrogen flame.A new method is used for searching and thinning interferometric fringes in the computer image processing of holographic interferograms.The temperature profiles of the flames are calculated from measurements of the fringe shift by solving Abel-type integral equation with the Laplace transform.The errors resulted from refraction of the probing rays in holographic interferometry of axisymmetric phase objects are discussed.A simple method is introduced to correct the refractive errors.The effects of the object composition and of small displacement errors of the interferometric fringes on holographic measurements of axisymmetric phase objects are considered too. |
