Abstract
This image tube converts irradiated electrons into fluorescence by irradiating electrons converted from a light beam by a photocathode onto a YAG crystal member. Since the YAG crystal member is a single unitary solid, the fluorescence generated on the input surface of the YAG crystal member contains no fixed pattern noise.
