Abstract:
The present invention provides a digital imaging photodetector with a gas electron multiplier. The digital imaging photodetector comprises a gas electron multiplier detector. The gas electron multiplier detector includes a photoelectric converter for converting incident light into photoelectrons or Compton electrons; a gas electron multiplier (GEM) for receiving the photoelectrons or Compton electrons from the photoelectric converter and multiplying them; and a readout unit for receiving an electrical signal indicating a position where an electron cloud multiplied in the gas electron multiplier arrives on an anode, recognizing coordinates of the electron cloud based on the received signal, and outputting the coordinates of the electron cloud. According to the digital imaging photodetector of the present invention, real-time imaging of image information can be achieved by multiplying photoelectrons or Compton electrons, which are discharged due to a photoelectric effect or a Compton effect induced by visible rays, ultraviolet rays or X-rays, using the gas electron multiplier.
