摘要

激光与物质的热作用是激光与物质作用的主要作用机制之一

激光辐照下探测器中半导体材料的温升对探测器性能具有很大影响.本文以碲镉汞探测器为例

建立了碲镉汞探测器在激光辐照下的非稳态热数学模型

利用MATLAB偏微分方程工具箱

采用有限元法

对探测器的温升进行了计算

实践证明该方法解决此类问题是简便而有效的.

Abstract

The paper describes a mathematical model of HgCdTe (PC) detectors irradiated with laser

and also introduces a method of thermal distribution using partial-differential equation toolbox of Matlab. In practice

it shows that this method is handy and effective in solving this kind of problem.
