| 摘 要： | 根据波前相因子判断法,推导出缝光源在不同位置经双棱镜所成的像。得出缝与双棱镜的棱脊严格平行时,两相干光源振幅相同,形成清晰干涉图样;当缝与棱脊不平行但位于同一平面时,缝像平行于缝,但两像振幅不同,一定条件下可形成不清晰的干涉图样;当缝不在同一平面内时,缝像仍平行于缝,但不能形成干涉。

| Abstract: | According to the wavefront phase-factors,it is deduced that when slot is parallel to biprism ridge the slot image situation and the interference circs.When slot and ridge is not parallel,but still in the same plan,the slot image is still parallel to the slot,in certain conditions can be formed interference.When the slot is not in the same plane,the slot image is not parallel to slot,they can not interfere. |
