Beschreibung
Zusammenfassung:	A visible light streak tube and an electron-optical imaging system. The visible light streak tube comprises a spherical cathode (1), a focusing electrode assembly (2), an anode diaphragm (3) and a planar fluorescent screen (4). The focusing electrode assembly (2) comprises at least two focusing electrodes (21, 22). The focusing electrodes (21, 22) are used to adjust a position of an image plane of an electron beam. The focusing electrode assembly (2) and the anode diaphragm (3) are both cylindrical structures. The spherical cathode (1), the focusing electrode assembly (2) and the anode diaphragm (3) are sequentially arranged and spaced apart from each other. The spherical cathode (1) is configured to fit with an electrostatic focusing structure resembling a concentric sphere. The planar fluorescent screen (4) is connected to one end of the anode diaphragm (3) away from the focusing electrode assembly (2) by means of a metal sleeve (5), and is used to receive an electron beam to form an image.
