Abstract
A streak tube the total length of which is short. An optical image of an object is converted into a plurality of divided micro incident electronic images by converting means and photoelectrons from these divided micro incident electronic images are focused by a focusing electron lens. Further, the photoelectrons are swept by a deflecting means and imaged on an output plane. Thus, the optical image of the object is converted into the divided micro incident electronic images, so that focusing and sweeping can be performed in short distance. Accordingly, the total length of the tube can be short.
