衍射波 meaning in English
diffracted wave
diffraction wave
Examples
- Alternatively, we can image that the incoming wave is diffracted by the object and the resulting diffracted wave is then diffracted again by the objective lens .
换一种方式，我们可以这样想象：入射波被物体反射，所得到的衍射波再一次受到物镜的衍射。 - The true image and the conjugate image of this hologram could n ' t be separated
这种全息图的1级衍射波是分不开的，这是第一代全息图。 - Where the diffracted wavelengths are 1 / 2 wave out of step for each of these colors , the waves destructively interfere
当这些颜色的衍射波的波长相差1 / 2波长时会产生相消的干涉。 - This method has some characters : during recording of the transmissive holograms the holographic grating placed in front of the holographic plate closefittingly is used as a spectroscope . the transmissive wave is served as the object wave and the diffraction wave through the holographic grating or the deflective reflect wave produced by the silicon slice is served as the reference wave , therefore the hologram is named as self - reference image hologram . the recording results are the off - axis holograms and the twin images can be separated successfully
在记录透射型全息图时，将全息光栅紧贴置于记录干板之前，而光栅起到了分光的作用，直透波作为全息图的物光波，参考光是物光通过光栅后产生的衍射波；记录反射型全息图时将硅片置于记录干板之后，利用反射硅片产生离轴参考光，因此系统仅需一束照明光束，参考光来自物光本身，因此称之为自参考像全息图。
