ELECTROMAGNETIC RADIATION DETECTOR ARRAY AND X-RAY IMAGE AMPLIFIER COMPRISING SUCH AN ARRAY

摘要

A matrix having photosensitive elements formed by thin-film technology on the same dielectric substrate and disposed at each crossing point of perpendicular lines and columns. An addressing MOS transistor, formed by thin-film technology and associated with each photosensitive element, receives periodically on its grid an enabling signal applied simultaneously to all the addressing transistors in the same line of photosensitive elements and is connected for transferring to a video amplifier the electric signals provided by each addressed line of photosensitive elements. An amplifier for these signals is associated with each photosensitive element and is formed by thin-film technology.
