An image sensor includes a scintillator comprising a substrate covered with a layer of luminescent material, the layer of luminescent material comprising a first side in contact with the substrate and a second side, the surface of which has asperities, separated by interstices, a detection radiation emerging from the second side of the layer of luminescent material when the luminescent material is illuminated by a probe radiation through the substrate, characterized in that the second side of the layer of luminescent material is covered with a film of a coating material partially absorbing the detection radiation, and moulding itself to the asperities of the surface of the second side of the layer of luminescent material.

Image sensor with enhanced spatial resolution and method of producing the sensor

The invention relates to the correction of the distortion of an image intensifier electron tube comprising an entry screen intended to receive what is called primary electromagnetic radiation and an exit screen emitting radiation dependent on the primary radiation, the entry screen including a photocathode that emits an electron beam in the tube toward the exit screen, the emission of the electron beam being dependent on the primary radiation. The entry screen furthermore includes a test pattern formed from a plurality of dots distributed over the entry screen, the test pattern comprising means for locally altering the electron beam without altering the primary radiation.
