Focal Plane Array

(array of receivers at the focus of a radio telescope)

A Focal Plane Array is an array (e.g., a grid) of radio receivers at the focus of a Radio Telescope, i.e., at its Focal Plane. Bolometers may be used as the receivers.

With it, Radio images can be made, as a photographic plate or CCD at the focal plane of an Optical telescope does.
