摘要
分析了高能激光内光路热晕的特点及传统热晕研究测量方法的缺点,提出了基于层析技术的气流折射率场的干涉测量原理和方法,利用该方法可以实现对高能激光系统内光路热晕的无耦合测量.通过对模拟热晕流场热晕的光学层析干涉测量,验证了该方法的可行性和可靠性.
Abstract
Computer tomography is widely used in density measurement, and this method is also introduced into analysis of airflow as optical tomography. The airflow characteristic of thermal blooming in high energy laser(HEL) beam and the disadvantage of traditional method are discussed. The optical tomography of thermal blooming is presented in this paper, and it can measure HEL inner beam thermal blooming non-intrusively. By the numerical simulation of tomographic optical HEL beam thermal blooming, the feasibility and dependability of this approach are tested.
