Patent abstract
A device and method are presented for use in measuring photon energy. The device comprises at least one pixel unit (10) including a Photocathode (12) that emits electrons in response to absorbed photons; an Anode (14); and a control unit (19) operable for controlling an electric current from the Photocathode (12) to the Anode (14) so as to selectively prevent electrons' arrival to the Anode (14) to thereby scan a spectrum of photon energies incident on the Photocathode (12).
