Based on the self-imaging effect of multimode interference couplers, general self-imaging positions are analyzed in detail.
根据多模干涉耦合器的自映像原理，对多模干涉耦合器的成像位置进行分析。
2
The analysis indicates that the self-imaging effect can be widened to the two-dimensional confinement on the basis of the one-dimensional confinement.
分析表明，一维限制多模干涉器的自镜像效应可以完全拓展到二维上。

The angular displacement of reflecting surface is measured in accordance with the direction change of Moire fringes caused by the inclination of grating. self-imaging plane.
