High Dynamic Range Streak Camera
C7700
v
The relaxation oscillation of a laser diode can be measured
with the C7700 under single shot operation.
(The data was captured with a C4880-21 readout CCD camera.)
Less than 60 ps
The C7700 is a newly developed high dynamic range
streak camera that can handle a large number of photo-
electrons. This feature enables single-shot
measurements of ultrafast phenomena with a D-range
as high as 10 000 : 1.
This system is suitable for high-precision simultaneous
measurement of high-intensity and weak intensity pulse
light.

[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.

UTILITY
The HPD-TA (Temporal Analayzer) is a high-perfomance digital
data acquisition and control system specifically designed to read-
out images from the phosphor screen of the HAMAMATSU
streak camera. It enables precise, quantitative acquisition and
preanalysis of two dimensional streak data that includes photon
counting plus a full range of data correction and calibration
possibilities. The HPD-TA allows the remote control of the
C7700 via GPIB interface. The entire system is controlled
through a powerful and user-friendly application software that
runs on a Microsoft Windows platform
