- W2066630897 abstract "Aperture synthesis allows a number of small apertures to operate cooperatively in the synthesis of a large full aperture telescope. For earth-based systems, the effects of atmospheric turbulence, which introduces time-varying aberrations, must somehow be corrected if good imagery is to be obtained. One correction scheme relies on a comparison, in a range of overlap, of correctly-phased spatial frequency components with new components that are in error by unknown piston (constant) and tip-tilt (linear) phase terms. Normally this method requires that the subapertures employed in the synthesis be sufficiently small that phase aberrations beyond piston and tip-tilt be ignorable. Through the exploitation of lucky imaging conditions, however, larger apertures can be used, with a subsequent increase in resolution and light-gathering power for the optical system." @default.
