围绕激光ＣＴ技术在柴油机喷雾测试上的应用进行研究，开发了一套柴油机喷雾的激光ＣＴ测试系统．应用脉冲激光和ＣＣＤ摄象机的特性，将柴油机喷雾图象实时采集到计算机图象处理系统上．最后，对１３５柴油机喷嘴的冲突喷雾进行了测量，用ＡＲＴ重建了三维喷雾图象，实现了燃油喷雾内部构造的可视化和三维相对浓度分布的测量．
Based on the application of laser CT technology in diesel engine spray test, a set of laser CT testing system for diesel engine spray was developed. Application of pulsed laser and CCD camera characteristics, real-time diesel engine spray images collected on the computer image processing system. Finally, the collision spray of 135 diesel engine nozzle was measured, and the three-dimensional spray image was reconstructed with ART to realize the visualization of the internal structure of the fuel spray and the measurement of the three-dimensional relative concentration distribution.
