双曝光全息术用于水平圆管温度场的重建
Reconstruction of temperature field around horizontal cylinder based on double-exposure holography
摘要
Abstract
Double-exposure holography is widely adopted in temperature field visualization because of the output of infinite fringes which directly present the wavefront distortion .When the wall temperature of the natural convection horizontal cylinder in 25mm diameter and 350mm length dropped from 72℃to 22℃, the simple interferometric fringes were obtained using the double-exposure holography to study temperature field .Stripe displacements at different angels were extracted by fringe center method .Peak values and valley values of R channel of interferogram were corresponding to the centers of bright and dark fringes .Distributions of fringe orders were achieved and temperature field was inversed .The maximum of relative error of wall temperature between inversion values and thermocouple measurement values was 0.059. The results show that the data of double-exposure holography is feasible and reliable .The study is helpful for simple and fast inversion of temperature field .关键词
