固体推进剂火焰中OH基的激光感生荧光(LIF)二维图像

Two-dimensional Images of OH Radicals in Flame of Solid Propellant Using Laser Induced Fluorescence (LIF)

用Nd∶YAG激光器抽运染料激光器 ,激发固体推进剂火焰内OH基火焰中V″=0→V′=1跃迁 ,用CCD收集V′=0→V″=0 跃迁的非共振感生荧光 ,测量了固体推进剂火焰中OH基的二维分布情况。

Nd:YAG laser pumped dye laser was used to excite the OH radicals in flame of solid propellant at the transition V''=0&rarrV'=1. The fluorescence at transition V'=0&rarrV''=0 was collected by CCD detecting system, and the two-dimensional images of the concentration of OH radicals in flame of solid propellant were obtained.
