The attainment of diffraction-limited images with large ground-based optical telescopes is an important objective for many astronomical programmes. The limited resolution set by atmospheric fluctuations in refractive index can be overcome by applying aperture synthesis and phase-closure techniques to short-exposure images taken through non-redundant aperture masks. The first optical images obtained with this technique are presented here. The diffraction limit is achieved with good dynamic range… 
Optical aperture synthesis with the Anglo-Australian telescope
We propose to construct an optical interferometer to produce high resolution images by aperture synthesis. The interferometer, known as the Masked Aperture Pupil-Plane Interference Telescope
Diffraction-limited imaging at IR wavelengths using aperture masks and fully filled apertures
The performance of a phase recovery algorithm developed for speckle data collected using a pupil-plane mask has been investigated for use at near-infrared wavelengths. The method, based on the
Visible-wavelength diffraction-limited imaging using low-order adaptive optics
We explore the possibilities and limitations of an adaptively corrected dilute-aperture optical telescope. In such a system a non-redundant pupil geometry is coupled with low degree-of- freedom
High dynamic range imaging by pupil single‐mode filtering and remapping
Because of atmospheric turbulence, obtaining high angular resolution images with a high dynamic range is difficult even in the near-infrared domain of wavelengths. We propose a novel technique to
The Coast Project
The Cambridge Optical Aperture Synthesis Telescope (COAST) is the first independent element Interferometer to produce an astronomical image. Resolutions of the order of 20 milliarcseconds (mas). are
Development of a high-dynamic range imaging instrument for a single telescope by a pupil remapping system
We present the laboratory demonstration of a very high-dynamic range imaging instrument FIRST (Fibered Imager foR Single Telescope). FIRST combines the techniques for aperture masking and a
Diffraction-limited imaging with partially redundant masks: II. Optical imaging of faint sources
In a recent paper [J. Opt. Soc. Am. A 9, 203 (1992)] the benefits of pupil apodization were examined for the near-infrared imaging of bright sources. In the current paper we extend these
Noise in optical synthesis images. I. Ideal Michelson interferometer
We study the distribution of noise in optical images produced by the aperture synthesis technique, in which the principal source of noise is the intrinsic shot noise of photoelectric detection. The
Diffraction-limited imaging with partially redundant masks. I. Infrared imaging of bright objects
TLDR
The decrease in redundancy resulting from apodizing the telescope pupil results in an enhancement of the quality of reconstructed images at high light levels, which is particularly valuable when short-term variations in the statistics of the atmosphere make the seeing calibration of speckle interferograms difficult.
Interferometric imaging with an aperture masked telescope
Since the invention of the telescope in the 1600’s, astronomers have been striving for a clearer definition of the objects they observe. This has led to the development of larger and larger
