基于吸收光谱技术的半导体激光传感器已被开发用于监测PDE流中的反应物和产物。我们已经证明了传感器在脉冲爆震发动机（PDE）上工作的液体JP-10和气态C2 H4燃料在空气和氧气。所测量的特性包括未燃烧和燃烧气体种类浓度、未燃烧和燃烧气体温度以及燃烧气体速度。传感器提供的信息已被用于验证计算爆震模型和推进发动机开发。一种新的乙烯摩尔分数传感器和一种新的水浓度传感器，分别使用1.6和1.4微米附近的快速扫描DFB激光器，显示出主动PDE控制的希望。
Diode-laser sensors based on absorption spectroscopy techniques have been developed for monitoring both reactants and products in PDE flows. We have demonstrated the sensors in pulse detonation engines (PDEs) operating on liquid-JP-10 and gaseous-C2H4 fuels in air and oxygen. The measured properties include unburned and burned gas species concentrations, unburned and burned gas temperature, and burned gas velocity. The information provided by the sensors has been used to verify computational detonation models and advance engine development. A new ethylene mole fraction sensor and a new water concentration sensor, using fast-scanning DFB lasers near 1.6 and 1.4 microns, respectively, show promise for active PDE control.
