Instantaneous phase retrieval with the vector vortex coronagraph - Theoretical and optical implementation
TL;DR: In this paper, a vector vortex coronagraph is used to measure the phase and amplitude of residual stellar speckles in coronagraphic images, which serve as a new type of phase diversity (POAM diversity), as well as an extension of the Nijboer-Zernike theory of aberrations.

TL;DR: In this paper, the working principle of liquid mirror telescopes is first recalled, along with the advantages and disadvantages of the latter over classical telescopes, and a description of the telescope, its instrumentation and the handling of the data is also presented.

TL;DR: In this article, a set of micro-interferometers are used to measure the angular diameter of the Sun and obtain fringe patterns similar to those that will be obtained with future large imaging arrays.

TL;DR: The 4m International Liquid Mirror Telescope project as mentioned in this paper was used for photometric monitoring of multiply imaged quasars, which has the virtue of accounting for all types of image configurations observed so far among the presently known gravitational lens systems.
