Abstract
An image analysis deviceis equipped with the photoreceptive meansthat optically acquires diffraction pattern A that appears on the fluorescent screenin order to obtain the diffraction pattern resulting from reflection high-energy electron diffraction, and the halation-prevention filterprovided so as to transmit the visible light emitted from the diffraction pattern A of the fluorescent screen, along the light path connecting the photoreceptive meansand the fluorescent screen. Also, the filteris varied so that the transmittance of the visible light transmitted through the filteris minimum at the filter center and increases with the distance from the center.
