spatially resolving detector

of radiation
A detector for the measurement of the spatial distribution of the radiation. Spatially resolving detectors can be divided into two groups:
  1. the photosensitive area consists of a matrix of discrete photosensitive elements, the pixels (picture elements) forming an array with the facility to separately read out the information, simultaneously or sequentially.
  2. the photosensitive area consists of a single photosensitive element that must be scanned (e.g. @I02943@.)
