Abstract
We propose a new electron emission type infrared light sensor, which is used a principle of a field emission from a PZT thin plate. The PZT thin plate acts a field emitter and an Aluminum(Al) is an anode electrode. The PZT plate was irradiated by infrared light in a vacuum chamber. The electron emission current was proportional to the incident infrared light energy. Using the principle, we fabricated prototype infrared light image sensor. This imager was constructed with the PZT photocathode, a Micro Channel Plate and a fluorescent substrate. An infrared light was irradiated to the whole PZT thin plate, and we confirmed a fluorescence of the PZT thin plate shape.Infrared Imager.
