Patent ID: 6940084

Claim:
A solid state radiation detector comprising: a first conducting layer having a transmissivity to recording light; a recording photoconductive layer exhibiting a photoconductivity by receiving irradiation of the recording light; a capacitor unit for storing, as latent image charges, charges of an amount in response to an amount of the recording light; a reading photoconductive layer exhibiting a photoconductivity by receiving irradiation of reading light; and a second conductive layer including a large number of optical charge pair generating linear electrodes having a transmissivity to the reading light and a large number of optical charge pair non-generating linear electrodes arranged alternately with the optical charge pair generating linear electrodes, the solid state radiation detector being composed by stacking the foregoing constituents in accordance with the order listed above, wherein, when a pair of the optical charge pair generating linear electrode and the optical charge pair non-generating linear electrode is defined as one cycle, the cycle ranges from 10 μm through 150 μm.
