An apparatus for translating an optical image, as of a waveform, created by an electron beam device such as a cathode-ray tube into an electric signal. A fiber optics faceplate, having a multiplicity of optical fibers laid parallel to one another, is held against the CRT screen for transmitting the optical image to an image sensor such as that comprised of charge-coupled devices. Although preferable to optical lens systems because of far less transmission loss, the fiber optics faceplate has been susceptible to the irregular electrification of its light-exit surface, resulting in the appearance of starlike bright dots upon image reproduction from the output from the image sensor. Such irregular electrification is avoided by providing a transparent layer of electrically conducting material between the fiber optics faceplate and the image sensor.
