Direct Optical Switching Technology

The X-ray sensor employs a direct switching method. The panel is comprised of a double layer of amorphous selenium. By extracting the image signal that is converted to an electric charge through our newly-developed Direct Optical Switching method rather than a TFT switch, we have reduced electronic noise and achieved a pixel pitch of 50µm.
