An image sensor cell is presented for detection of electromagnetic radiation. The sensor cell can be used as a pixel in the pixel matrix of an image sensor device. The image sensor cell comprises a photocathode (101), an electrode arrangement (102), and a control unit (16). The electrodes' arrangement is configured for defining multiple spaced apart locations for collecting electrically charged particles emitted from said source of charged particles. The control unit is connected to the electrodes' arrangement and adapted for measuring electrical charge collected at each of said locations, spatial distribution of the collected electrical charge being indicative of profile of electromagnetic radiation causing the emission of said collected charged particles.
