Constructing Telescopes that Avoid Resolution Limits for 100X Better Imaging Resolution
by Brian Wang from NextBigFuture.com on (#6E6HG)
According to the widely accepted Rayleigh criterion, in order to resolve two distant point sources, their angular separation must be larger than 1.22 (the wavelength of light divided by the telescope's aperture diameter. To achieve higher resolutions, telescope systems with ever larger primary mirrors are therefore being designed, making them extremely expensive and technologically challenging ...
