Adaptive Optics & Interferometry: Foundations

Adaptive optics and interferometry are two different techniques for improving angular detail. Adaptive optics is powerful for near-infrared and visible ground-based imaging of compact targets, while interferometry enables extremely high-resolution radio, millimeter, and selected optical observations.

Adaptive optics and interferometry are two different techniques for improving angular detail.

supported

Adaptive optics measures wavefront errors many times per second and reshapes a mirror to apply the opposite distortion.

supported

Corrected images show narrower point-spread functions and higher Strehl ratios than uncorrected images.
