Abstract
An electron-optical image tube is provided which avoids the limitations imposed by photographic and image storage techniques and which enables a direct linear intensity profile of a pulse train to be obtained. The image tube, instead of having a phosphor screen, has a disc with one or more slit apertures therethrough and a photoelectron image is scanned across the aperture or apertures. The time spacing of the light pulses can be adjusted so that the time of the image tube coincides with the fixed aperture or apertures in the disc when a continuous circular scan is used.
