FIELD: optical signal conversion, scaling, and amplification. SUBSTANCE: optical image converter has electrostatic focusing system, spherical photocathode, and planar screen; dimensions of its components are chosen so that quasi-planar image is shaped. In addition, axial focusing electrode is inserted between anode and screen for image shaping. EFFECT: improved image shaping. 2 cl, 2 dwg , t tbl
