| 摘 要： | 本文介绍在4F体系中,用白光照明下,把两块相同的位移光栅,平行叠加放在物面上,由于两块光栅相对位移,引起谱面上谱斑相移,在谱面上选两个谱斑作干涉的次波波源,在像面上可获得干涉图样的实验方法和理论分析.

| Abstract: | In this paper it is described that phase shift of spectrum disk in a spectrum -face is due to relative shift between two identical phase -gratings, which are of equal rank and overlap on the body surface in 4 F system in illumination of white - light. Interference figure is got while two selected spectrum disks do secondary wave source in the image - face. Besiddes, the theoretical analysis is accomplished for the experimental method. |
