摘要：The contrast ratio of an image intensifier of the photocathode- amplifier-phosphor type is increased by using a fiber optic plate of which the thickness is reducedto such extent that the plate may not be able to function as a vacuum seal or an electricalinsulator when a typical voltage for the operation of the intensifier is applied to thephosphor layer. This relatively thin fiber optic plate is placed entirely inside a vacuum,protected from the atmospheric pressure by a thick output window plate which isoptically transparent.
