Abstract
A synchronous scan streaking device comprising a photoelectric layer, an electronic lens, an anode with an aperture, a pair of deflection electrodes, and a phosphor layer arranged in order within a vacuum envelope. A deflection voltage at the same frequency as the repetition rate of the light pulses incident on the phosphor layer to be measured is fed from deflection voltage generation means to the deflection electrodes so as to repetitively generate an enhanced image of the incident light on the phosphor layer. At least one shielding metal structure which is connected to the common potential source is arranged in the space between the deflection electrode plate and the wall of the envelope, and surrounding a deflection electrode plate lead provided to connect the deflection electrode plate through the envelope to the deflection voltage generation means.
