Charge read-out structure for a photon / particle detector

A spatially-resolving charge detection device comprising:

• a continuous resistive layer configured to capture a charge incident thereon and being capacitively coupled to at least one two-dimensional planar array of discrete electrodes which are electrically insulated from one another and positioned behind the continuous resistive layer relative to the incident charge, each electrode in the array being capacitively coupled to an adjacent electrode in the array to form a capacitively coupled network of electrodes,
• selected ones of the electrodes in the array each being coupled to an array output for connection to a respective charge measurement device,
• the continuous resistive layer having a resistivity sufficient to temporarily localize the captured charge to an area corresponding to a subset of said electrodes in the array to form a capacitively induced charge thereon for a duration sufficient for signal measurement from the array of electrodes by the charge measurement devices,
• wherein the capacitive coupling of the electrodes in the array results in division of the capacitively induced charge among the electrodes such that a spatial position of the charge localized on the continuous resistive layer can be determined based on the relative outputs of the charge measurement devices.
