Interferometry technique

Optical Interferometry

Combining the light of separate optical or infrared telescopes to reach angular resolutions no single telescope could — far harder than in the radio because the light waves must be kept in step to a fraction of their wavelength. The VLT's four unit telescopes can be combined this way.
