[Operating Principle]
The light pulse to be measured is focused onto the photocathode
of the streak tube through the slit, where the photons are con-
verted into a number of electrons proportional to the intensity of
the incident light. These electrons are accelerated and conducted
towards the phosphor screen, and a high-speed voltage which is
synchronized to the incident light is applied. The electrons are
swept at high speed from top to bottom, after which they are bom-
barded against the phosphor screen of the streak tube and con-
verted to an optical image.
When the light intensity of the streak image is very weak, an image
intensifier or an image booster amplifies the low light level streak
image.

*[About a Dynamic Range]
The maximum dynamic range of the streak camera essence is set to
1000:1 by the measurement condition of temporal resolution 5ps, and
is set to 10 000:1 by the measurement condition of temporal-resolution
100ps. With a light intensity, the image intensifier tube, such as an
image intensifier or an image booster, is combined with a streak
camera. In this case, the image intensifier tube may restrict the
dynamic range of the measurement system. Furthermore, a read-out
camera may also restrict the dynamic range of the measurement
system.
