The invention concerns a device and method for two-dimensional imaging and timing of particles or electromagnetic radiation with improved pulse-pair resolution. A detector, e.g. a michrochannel plate detector with a delay-line anode with three or more conductive members is used as exemplary embodiment for achieving these requirements. Redundant position and timing information is used for uniquely determine the timing and position of two or more particles, even if they arrive at the same time at the detector.
