Abstract: A light sensor may include an array of light sensitive elements and an array of transmissive filters provided over the array of light sensitive elements and in substantial registration therewith. The array of transmissive filters comprises an infrared transmissive filter that substantially transmits infrared light and substantially blocks visible light as well as at least one non-infrared transmissive filter that substantially transmits non-infrared light.

Abstract: The scintillating screen of digital imaging systems used in conventional transmission electron microscopy is discretized and the scintillating material is contained in a cellular structure having a geometry judiciously selected for coupling to the optical channels of the imaging system. This allows optical matching, without smearing, between the elements of the scintillating screen and the discrete light-collecting and light-registering optical channels of the system. Cross-talk among optical channels is consequently minimized and the resulting light-imaging resolution of the digital imaging system is optimized.
