SIPM ARRAY SIGNAL READING METHOD, APPARATUS AND SIPM ARRAY MODULE

摘要

A SiPM array signal reading method, an apparatus and a SiPM array module, the method comprising: when a SiPM unit on a SiPM array collects an optical signal, converting the optical signal into a current signal by means of the SiPM unit (S101); by means of an electrically conductive medium layer connected to the SiPM unit, distributing the current signal to read electrodes disposed on the electrically conductive medium layer (S102); outputting the current signal by means of the read electrodes (S103); according to a current output of each read electrode, determining position information of the SiPM unit on the SiPM array (S104). Thus, by means of an electrically conductive medium layer and read electrodes on a SiPM array substrate, as well as not using discrete elements such as resistors and capacitors on the electrically conductive medium layer, redesign of elements is not necessary when changing the size of a SiPM array, effectively improving SiPM array read channel compression results, and facilitating expansion and integration of SiPM arrays.
