Abstract
New types of devices for measuring two-dimensional photon-caused or corpuscular-ray-caused image signals by means of a special television imaging technology suitable for an extremely low level of incident visible light, infra-red, ultra-violet, X-rays, .gamma.-rays, protons or neutrons are disclosed. These image signals are sensed by an electron emitting layer, i.e., a photoelectric emitter or a secondary electron emitter, which can respond to photons or corpuscular rays, and then amplified by a micro-channel-plate which can multiply the emitted electrons to a finite number with their positional relationships remaining in the two-dimensional area. The amplified signals are digitally processed to be displayed on a television picture monitor. The image signals on the television picture monitor can be printed out or saved in magnetic media.
