气溶胶吸收直接影响光在大气中的传播造成光的衰减。本文采用折返式 Jamin偏振干涉结构建立了气溶胶光热干涉实验系统, 提出并实验研究了在激光照射 (加热)和降温两个阶段分别测量吸收系数的方法, 确定了两种方法测量气溶胶吸收系数的激发激光功率, 为进一步开展气溶胶吸收系数的实验研究提供了参数支持。

The aerosol absorption directly influences the spread of light in the atmosphere, and causes the attenuation of light. With advanced folding Jamin interferometer, the interference system is completely set up. During laser heat and cool process, aerosol absorption can be obtained differently. The parameter of laser exciting power has been determined. It is shown that the system of aerosol absorption coefficient is feasible.
