摘要：A newly developed camera is proposed that uses two types of devices-gallium arsenide phosphorus (GaAsP) to provide a high level of quantum efficiency in the visible light region and gallium arsenide (GaAs) to provide a high level of quantum efficiency in the near infrared region-in the photocathode of a proximity type image intensifier (I.I). We have discovered that image burning, which has been a problem with the photoelectric surface in a conventional I.I, can be halved by increasing the resistance of a micro-channel plate. We have developed a noise-reduction circuit capable of eliminating feedback ion noise by taking into account its characteristics. We have also developed a lens and a prism that has an enhanced ability to allow more near-infrared rays to pass through. In actual imaging experiments, we were able to take quality images of animals in conditions without moonlight.
