Image sensor has a spatial resolution improved and advantages of the sensor

摘要

The present invention relates to an image sensor. It also relates to a method of manufacturing such a sensor. The image sensor comprises a scintillator (1) comprising a substrate (3) coated with a layer of luminescent material (4), the layer of luminescent material having a first face (15) in contact with the substrate and a second face (16), whose surface has asperities (5), separated by gaps (7), a detection radiation emerging from the second face of the layer of luminescent material when the luminescent material is illuminated by a probe radiation through the substrate, characterized in that the second face of the layer of luminescent material is covered with a film of a coating material (9) partially absorbing the detection radiation, and matching the asperities of the surface of the second face of the layer of luminescent material.
