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（Ｃｈａｒｇｅｃｏｕｐｌｅｄｄｅｖｉｃｅ）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。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.
