Abstract:
1. An electronic pulse detection device comprising: a plurality of electron amplifying parts arranged in matrix and configured to increase the number of incident electrons; electrode parts which are provided to correspond to said respective plural electron amplifying parts and on which the electrons from said electron amplifying parts are incident; a plurality of switch parts provided to correspond to said respective electrode parts, the switch parts on a same row and on a same column being connected to one another, and the mutually connected switch parts on the same row or on the same column being turned on/off as a unit; a current-voltage converting part to which said switch parts are connected and which is configured to convert a current due to the electrons incident on said electrode parts to a voltage when the switch parts are turned on; and a plurality of switch circuit parts each provided to correspond to each row or each column of said switch parts connected to one another, and each configured, when turned on, to connect said switch parts of the same row or the same column to said current-voltage converting part as a unit and when turned off, to ground said switch parts of the same row or the same column as a unit; and an operation switchover part connected to said switch parts and said plural switch circuits and configured to turn on/off said switch parts on the same row or the same column that are turned on/off simultaneously and said switch circuits based on a quadrature modulation pattern.
