ABSTRACT:
An improved optical fiber cathode ray tube is provided which enables the recording of images on a recording medium with a high resolution even if the recording medium is disposed with an increased gap between the tube and the recording medium to prevent mechanical contact therebetween. The tube is provided with an additional stack of optical fibers facing the optical fiber face plate of the cathode ray tube with a light transparent thin layer being interposed between the face plate and the additional stack. The transparent thin layer may be a transparent plate and/or air gap. The stack of optical fibers may be in a form of an optical fiber plate or bundle.
