The invention relates to a photoelectric scanning head which can conduct point scanning for overlook image and perspective image. The scanning head comprises a faceplate with a scanning objective and a fixed shell provided with an aperture and a photoelectric inverter. With help of an agile adjusting element, the faceplate with scanning objective can move along the optical shaft of the scanning objective and acquire the best definition of image for image intensity and focalizing range which is constantly in the focalizing plane of the image. In scanning of overlook image, an irradiating system is arranged on the faceplate; the optical shaft penetrates the focalizing range of the scanning objective and gains the best supplementary irradiation for the overlook image. |
