燃油喷雾内部构造可视化的激光CT技术(2)——对柴油机喷雾的应用

Visualization of internal structure of fuel spray using laser computed tomography technique(2)——Applied to diesel spray

摘要: 本文介绍了作者设计的燃油喷雾的激光CT测试系统,其中采用红宝石脉冲激光器作光源,CCD(Charge coupled device)摄象机作探测器,并配置了P540数字图象处理系统。利用红宝石脉冲激光和CCD的特性,实时地将燃油喷雾采集到数字图象处理系统上。用ART对喷雾图象进行重建,成功地实现了燃油喷雾内部构造的三维可视化。

Abstract: This paper presents LCT(Laser Computed Tomography) measurement system of diesel spray,which includes a pulse ruby laser as the light source,a CCD video camera as the detector and the P540 digital image processing system as image storage device.Using the characteristics of ruby laser and CCD video camera,the fuel spray images were grabbed by the digital image processing system in real time.ART was used to reconstruct the fuel spray images and the three dimentional visualization of internal structure of fuel spray was realized.
