摘要
利用激光全息干涉原理测量酒精灯火焰温度分布,通过二次曝光的方法,获得了酒精灯火焰干涉条纹。利用Matlab数字图像处理技术,对干涉图像进行了简单的处理,实现了对火焰干涉条纹位置的准确判读。根据环带法和环带内折射率定常假设,并采用计算机辅助编程计算,对酒精灯温度场进行反演,对各级条纹对应的温度值进行标定,获得了酒精灯火焰温度场的分布规律。
Measured the temperature of alcohol lamp flame with the laser holographic interference technique.With the method of secondary exposure,the flame interference fringe of the alcohol lamp is obtained.Using the Matlab digital image processing technique,the interference image is simply processed,and obtained the accurate location of the interference pattern of flame.According to the band methods,and used the computer program calculation,the alcohol lamp temperature field is inversed.Finally calibrated the temperature of the flame,and the temperature distribution of alcohol lamp flame is obtained.
