    摘要： A high sensitivity light control system for providing relatively constant effective values of light intensity to photographic devices operating in very low levels of light intensity is provided by using the signal derived by integrating, amplifying, and smoothing the output of a periodically readout storage light detector tube to control a mechanical aperture, scanning frame time, or light gain in a variable gain image intensifier stage. Light intensities from the scene photographically viewed are detected and integrated temporally in the storage light detector tube, integrating the output of the storage light detector provides spatial integration of the temporally integrated light intensity over the scene viewed.

    摘要： By using the delay time incurred in image reproduction brought about by the convolution action of the phosphor in image converter tubes, time is obtained in which to turn off the reproduction of the image or to lower the reproduction intensity so that the intensity of the oncoming image will not damage a camera tube or overexpose photographic film. Conversely, time may be achieved in which to turn the image on, likewise to a camera tube or photographic film, or reproducing or recording a fastacting phenomenon such as a lightning flash or bomb burst without the necessity of wasteful continuous exposure in order to ''''catch'''' the desired image.
