A seeker includes a detection array having at least 2500 sensing pixels arranged in rows by row request lines and in columns by column request lines. At least one pixel includes an electromagnetic radiation sensor to trigger the pixel in response to sensing a triggering quantity of electromagnetic radiation, a row request circuit to send a row request after the pixel triggers, and a column request circuit to send a column request after the pixel triggers. The seeker further includes a row receiver to receive the row requests, a column receiver to receive the column requests, and a sequencer to receive, for each triggering pixel, the row of the row request and the column of the column request, and to generate an event including the received row and column of the pixel. The seeker also includes a time stamper to generate a time stamp for the generated event.
