Scintillometry

(measuring of twinkling)

Scintillometry is measurement of Scintillation (with a Scintillometer), e.g., the Twinkling of stars as seen from Earth. Its measurement helps planning the location of telescopes and, at least in principle, provides input for Adaptive Optics (AO) systems.

Measurement of scintillations produced by astronomical dust and gases can be used in observation, and distant, widely-spaced scintillation has been used as an Interferometer on a very large scale, for viewing Pulsars (PSR). In effect, this is using the Interstellar Medium (ISM) or Interstellar Plasma as a telescope.
