Photon sharpening

Abstract

The present invention provides an array of pixels for the detection of a flash of electromagnetic radiation or a cloud of impinging high energy particles. Each pixel in the array comprises a radiation receptor for converting the electromagnetic radiation or impinging high energy particles into a radiation signal, and a converter for converting the radiation signal into pulses. The array further comprises a circuit for comparing one or more of the criteria pulse amplitude, pulse arrival time, time to convert a pulse in a digital signal, pulse duration time, pulse rise and fall time or integral of pulse over time for pulses coinciding on pixels in a predetermined neighborhood. The array also comprises a circuit for suppressing those pulses that are compared negatively versus the corresponding pulses in another pixel of the neighborhood for the same one or more criteria. A corresponding method is also provided.
