Speckle Interferometers

Scientific paper

Speckle interferometry has now been shown capable of yielding diffraction limited information on objects as faint as visual magnitude 16. The instrumentation proposed will improve spatial resolution at visible wavelengths to approximately 15 milliarc-seconds (75×10-9radians, the best possible for any existing telescope), reduce detector induced image distortion to less than 1% and increase the throughput to essentially real-time complex Fourier transform amplitude and phase integrations at the telescope.
