摘　　要：根据相干场成像技术(又称傅里叶望远镜)接收镜的特点,研究了接收镜偏差对相干场成像技术光学传递函数的影响,推导了光学传递函数与接收光路光程均方差的关系式.该式表明相干场成像技术的光学传递函数是接收光路光程均方差与频差乘积的平方的负指数函数.为确定接收系统精度提供了理论依据.According to the feature of receptor system of coherent field imaging technique, also known as Fourier telescope, the influence of the deviation of receptors on optical transfer function （OTF） of coherent field imaging technique is investigated, and the relation between OTF and optical distance mean square deviation of receptor is also derived, which indicates that the OTF of coherent field imaging technique is a negative index function of square of product of optical distance mean square deviation and frequency difference. It can provide theoretical basis of determining the accuracy of receptor system.
