New device, telescope-interferometer (TI), for astronomical observations is proposed. TI has the main advantage of pupil plane interferometry techniques, namely diffraction-limited resolution, which is twice as much than it may be obtained in the focal plane of telescope of the same aperture. At the same time, proposed techniques has a minimum of all possible distortions introduced under measurements. Main limitation of TI is necessity to scan the object plane. At every instant TI builds an image of one point of object observed only.
