摘要
研制了一套拉曼激发激光诱导电子荧光空气流场测速系统 ,利用Nd∶YAG激光器的二次谐波及其抽运的氧气受激拉曼散射作为标记光源 ,以ArF准分子激光作为荧光再现光源 ,并用像增强CCD摄像机 (ICCD)记录荧光图像 ,成功地获得了纯氧及空气中的标记线的荧光图像 。
The Raman excitation plus laser induced electronic fluorescence air flow velocimetry system was constructed. The second harmonics of Nd: YAG laser and stimulated Raman scattering in O2 were employed as 'tagging' laser source. The tagged line was interrogated with an ArF excimer laser. The laser-induced fluorescence images from tagged lines in O2 and air were captured by an intensity-CCD Camera. The velocity measurement of O2 jet was carried out.
