摘　　要：从惠更斯—菲涅耳原理出发 ,根据光学综合成像像面干涉的实际情况 ,建立了符合实际的光学综合孔径像面干涉数学模型 ;根据针孔干涉的条件 ,把望远镜镜面分成许多子镜面 ,并在此基础上对光学综合孔径像面干涉进行了公式推导和计算机仿真 ;分析了两望远镜的波面倾斜及光程差对干涉条纹的影响 ,并进行了仿真 .According to image-plane interference status of optical aperture synthesis (OAS) and Huyges-Fresnel theory, a mathematical method is set up which fits with the true condition. By dividing telescope mirror into many small fragments with pinhole interference conditions, OAS image-plane interference formula is deduced according to fragments interference with each other, and OAS image-plane interference computer simulation is done. The influence of wavefront tilt and optical path difference is analyzed and simulated in the end.
