摘要 将数个小口径望远镜对准观测目标,测量两两小口径望远镜之间相干强度的大小和相位,只要得到足够数目的相干强度值.就可以借助傅里叶逆变换来得到观测目标的图像,所得图像的分辨率大大高于单口径望远镜的分辨率.光综合孔径成像原理及实现过程可以用图示法清楚地表示出来.图3,参6. Measuring the quantity and phase of the coherence degree between any couple of small telescopes which aim at the source,by means of inverse Fourier transform we can obtain the source image which is much sharper than that from a single telescope,if enough number of degree of coherence of the are provided.Moreover,the theory and the practical courses of the image reconstruction of the optical synthesis aperture system are clearly demonstrated by a series of figures.3figs.,6refs.
