Radiation astronomy/Detectors
[[Image:Detectors summary 3.png|thumb|right|200px|This tree diagram shows the relationship between types and classification of most common particle detectors. Credit: [[commons:User:Wdcf|Wdcf]].]]
'''Radiation detectors''' provide a signal that is converted to an electric current. The device is designed so that the current provided is proportional to the characteristics of the incident radiation.

These time differences were minute, but the improvement in electronics made it possible to measure them accurately and identify the presence of metal at a reasonable distance. These new machines had one major advantage: they were completely impervious to the effects of mineralization, and rings and other jewelry could now be located even under highly-mineralized black sand."<ref name="MetalDetector"/>

"A ''sun sensor'' is a device that senses the direction to the [[Sun (star)|Sun]]. This can be as simple as some [[w:solar cell|solar cell]]s and shades, or as complex as a steerable [[w:telescope|telescope]], depending on mission requirements."<ref name="AttitudeControl"/>
