ABSTRACT:
A streak tube comprising a photocathode for converting an optical image into a photoelectron beam, accelerating means for accelerating the photoelectron beam, deflecting means for deflecting the accelerated photoelectron means, focusing means for focusing the deflected photoelectron beam and a phosphor screen for receiving the focused photoelectron beam and forming a streak image corresponding to the optical image. The photoelectron beam emitted from the photocathode is deflected immediately after accelerated by the accelerating means, and subsequently is focused on the phosphor screen, to thereby eliminate the spread of the photoelectron beam on the phosphor screen upon sweeping of the photoelectron beam.
