This streak tube is unique due to linearly changeable voltage supplying on one pair of deflecting plates leads to a formation of streak or multiframe sweeps of a registered process image. Moreover total duration of three frames is approximately equal to the streak sweep duration. Since linearly changeable voltage is used instead of the multistage one  frame sequence duration can be achieved up to 1010GHz withing frame duration less then 100 ps.

The streak tube has a portable (manipulated) photocathode, an accelerating electrode, three pairs of deflecting plates which are used for high-speed image sweep and designed as through-pass elements of passband communicational lines with coaxial 50 Ohm connectors, a 3-hole framing aperture, two pairs of low-frequency plates used for an establishment of frames distances and a blue/green screen applied on a fiber-optics disk.
