Patent ID: 7476838

Claim:
A photoelectric imaging sensor comprising: a photo cathode converting an incident light into photoelectrons; a photomultiplier, kept vacuum inside thereof, intensifying photoelectrons converted by said photo cathode; an two-dimensional output electrode array arranged in a plane comprising plate electrodes at which photoelectrons intensified by said photomultiplier arrive; and connecting means for electrically connecting said output electrode array to pick-up electrodes arranged outside said photomultiplier, wherein said output electrodes array comprises: a plurality of plate electrodes in an array arrangment at a first side of the output electrode array; another plurality of plate electrodes in an array arrangment at a second side of the output electrode array, each of the plate electrodes corresponding to one of the plate electrodes at the first side of the output electrode array; and support electrodes electrically connecting each of the corresponding plate electrodes at the first side and at the second side.
