| Abstract: | 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. |
| Keywords: | aperture synthesis Van Cittert-Zernik theorem degree of coherence (u v) spectrum |
