A real-time laser particulate detector which is well suited for measuring the concentration of particles in FCC gas streams was developed by using aser and near-forword light-scatter technique.

介绍了利用激光及正前向光散射技术研制的一种激光粒子浓度监测仪，它适用于催化裂化装置烟气粉尘浓度的实时监测。

The result showed that EDTA with high concentration has evident effect on light scatter of KDP crystal but not laser damage threshold and homogeneity.

结果表明，高浓度EDTA对KDP晶体光散射有明显的影响，但对光学均匀性和光损伤阈值无明显影响。

For the camera, a laser pulse is fired at a wall, and the impact of hitting the wall causes the particles of light to scatter.
