For an ideal coherent light, the chief factor that affects fringe visibility is light intensity.
对于理想的相干光，影响干涉条纹可见度的主要因素是光波的光强。
3
On the basis of structure design of optical system and parameter option of optical components, the visibility of interference fringe with zero background intensity is optimized.
