Title:
二次元放射線検出器
Document Type and Number:
Japanese Patent JP4254602
Kind Code:
B2
Abstract:
A radiation detector is provided that has no fluctuations in detection sensitivity and is capable of suppressing the influence of the noise emitted from a light source. In the radiation detector in the present invention, a light emitting unit applies light to the end face of a flat light guide. On receiving the light, the flat light guide emits flat light from its surface toward an active matrix substrate. The light is led to a semiconductor thick film after passing through the active matrix substrate. The noise emitted from the light emitting unit to the active matrix substrate or the semiconductor thick film can be blocked by an electromagnetic shield. An incident radiation to the semiconductor thick film in this condition can be detected while the effect of the noise emitted from the light emitting unit is suppressed, and fluctuations in radiation sensitivity do not occur.
