| 摘 要： | 为了用热图法测量高能激光强度的时空分布,设计了将半导体制冷片作为激光靶屏的测量方案。研制了由16个50 mm×50 mm的制冷片组装成的总面积为200 mm×200 mm、总制冷功率超4 800 W的靶屏, 屏四周安装了8个红外标定物用于校正红外图像的畸变。理论上用热传导方程建立了激光辐照半导体制冷片靶屏的加热模型;数值模拟了屏表面温度分布同光强分布的关系，论证了氧化铝陶瓷材料制成的半导体制冷片作为高能激光靶屏的可行性，以及制冷片的制冷功能对测试性能的改善;通过实验验证了研制的靶屏测量光强是可行的。

| Abstract: | To measure far field intensity distribution of high energy laser by thermal image method,we studied a laser screen made of thermoelectric cooling chips(TECC).We first built heating model of target surface by laser irradiation based on heat conduction equation,then found out the relationship between the temperature of target surface and the laser intensity.We proved the feasibility of using the TECC made of alumina ceramic as target screen and studied the improvement of measurement with cooling function.We d... |
