Abstract

A fast temperature diagnostic for time-resolved measurements in harsh environments based on an acousto-optically modulated quantum cascade laser is demonstrated in shock-heated mixtures of carbon monoxide. The temperature measurements made with this system are largely insensitive to beam steering noise.

时间分辨，激光吸收温度测量在冲击加热混合物与减少光束转向和发射噪声

在冲击加热的一氧化碳混合物中，基于声光调制量子级联激光器进行了恶劣环境下时间分辨测量的快速温度诊断。用该系统进行的温度测量对波束转向噪声基本上不敏感。
