| 摘 要： | 提出了一种新的测量温度场的光学方法，即像面全息二次曝光法．利用该方法，测量并分析了轴对称温度场的分布情况．结果表明，该方法可以减小检测时反射波的影响．通过增强物光强度，可以提高干涉图样的对比度．同时在白光下可再现温度场的干涉条纹，从而得到不同输入功率下直线热源的干涉图样，实现了温度场的可视化．

| Abstract: | A new optical method of temperature field measure using image plane hologram with two times of exposure is presented. It can decrease the influence of reflected wave in measuring. Also it can increase the intensity of object light and the contrast of interference fringes. Moreover the interference fringes of temperature field can be reproduced in white light. By using this method, the interference fringes of temperature field of straight_line heat source under different input power are gained and the temperature field can be viewed. The distribution of axial symmetry temperature field is analyzed. |
