It is learned from elementary textbooks that the angular resolution of a perfect optical
telescope is limited by diffraction to an angle in radians of about A ID, the ratio of the …

There is much recent interest in the application of optical interferometric techniques to
problems of imaging through the earth's atmosphere, with particular application to …

DIFFRACTION-LIMITED IMAGING OF STELLAR OBJECTS USING TELESCOPES OF LOW
OPTICAL QUALITY JC DAINTY 1. Introduction Labeyrie has Page 1 Volume I, number 2 …

T he unaided eye has an angular resolution of about 1 arcminute. From the invention of the
telescope in the 17th century to the middle of the 1970s, astronomers improved on this …

Stellar interferometry may be defined as the art of utilizing interference effects for improving
the angular resolution of stellar observations. Resolution is improved in two ways:(a) …

Taking a sequence of speckle images of an astronomical object, the brightest point in each
image is shifted to the centre of image space and all images are superimposed. This …

We propose a new instrumental concept for long-baseline optical single-mode
interferometry using integrated optics which were developed for telecommunication. Visible …

An understanding of some of the physical bases of interferometric imaging can be helpful
both in designing and understanding interferometric telescope arrays and in planning …

In the first part of this review we survey the role optical/infrared interferometry now plays in
ground–based astronomy. We discuss in turn the origins of astronomical interferometry, the …

We show star images obtained with a miniature “densified pupil imaging interferometer” also
called a hyper-telescope. The formation of such images violates a “golden rule of imaging …
