了研究管材激光有氧切割过程和切割表面条纹形成模型。
The basic steps of the laser interferometric imaging is as follows: firstly, forming laser interference fringes in a certain space; secondly, the scattered light is yielded from an object which travels across the interference field, then a detector is employed to detect the scattered light; finally the image is reconstructed through certain processes to the scattering light.
激光干涉成像的基本方式是,利用激光在空域形成干涉条纹场,当目标同条纹场间有相对运动动时,其产生的回波信号强度会发生变化,利用探测器探测回波强度,再将此强度信号进行处理,便可获得目标强度反射率分布函数,达到还原像的目的。
