Interferometer arrays produced the first extremely high-resolution images using aperture synthesis at radio, infrared and optical wavelengths.

Many modern "telescopes" actually consist of arrays of telescopes working together to provide higher resolution through aperture synthesis.

Newer aperture synthesis radio telescopes are especially affected by this as they "see" a much larger portion of the sky and thus the ionosphere.

This technique is known as aperture synthesis or synthesis imaging.

The Australia group laid out the principles of aperture synthesis in their ground-breaking paper submitted in mid 1946 and published in 1947.

The LBT telescope baseline is via aperture synthesis.

Recently, it has become practical to perform aperture synthesis with arrays of optical telescopes.
