Streak cameras are high-speed light detectors
which enable direct measurement of light phe-
nomena with unsurpassed temporal resolution.
They can simultaneously measure time, posi-
tion (or wavelength) and light intensity, and
process the data in real-time using a dedicated
read-out system.
The Streak Camera C2830 can be equipped
with either of two plug-ins: a fast-speed (for
better than 10 ps resolution) or a slow-speed
(for better than 100 ps resolution) sweep unit. In
addition, C2830 has a 100 ns high-speed elec-
tronic shutter which eliminates unnecessary
incident light during the nonsweep period and
makes it possible to do sampling measure-
ments on continuous phenomena.

SYSTEM CONFIGURATION
OPERATING PRINCIPLE
The streak camera converts incident light into electrons and
performs a high-speed sweep (deflecting electrons from top to
bottom), enabling detection of the time variation of the incident
light intensity by converting these into different positions on the
screen. The figure below shows the operating principle of the
streak tube, which forms the heart of the streak camera.
The light pulse to be measured is focused onto the photocath-
ode of the streak tube through the slit, where the photons are
converted into a number of electrons proportional to the inten-
sity 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 and
are then multipled in the MCP (micro-channel plate), after which
they are bombarded against the phosphor screen of the streak
tube and converted to an optical image.
The optical image which appears on the phosphor screen is
called a streak image, and shows the intensity distribution of the
incident light, by which the positions of the electrons can be

determined in the perpendicular direction over the passage of
time. Using this method, the temporal intensity distribution of
the light being measured can be displayed as the spatial
intensity distribution on the phosphor screen.

Readout System*
q
HPD-TA
The HPD-TA (Temporal Analyzer) is a high-performance digital data
acquisition and control system specifically designed to read out images
from the Hamamatsu streak camera's phosphor screen. It enables
precise, quantitative acquisition and pre-analysis of two dimensional
streak data that includes photon counting plus a full range of data
correction and calibration possibilities. It possible to select the best
camera for a given streak configuration and application. The camera is
connected to an IBM-compatible PC/AT via a frame grabber board that
can support real-time data transfer.
The entire system is controlled through a powerful but user-friendly
software application that runs on a Microsoft Windows platform.
* A read out system based on the
computer is also available.
Please consult with our sales office for more details.
