Technical content

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.

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 Optical intensity Time Space Trigger signal Slit Lens Incident light Photocathode (photons → electrons) Phosphor screen (electrons → light) MCP (which multiplies electrons) Streak image on phosphor screen Time Space Sweep electrode (where electrons are swept in the direction from top to bottom) Sweep circuit Accelerating electrode (where electrons are accelerated) The intensity of the incident light can be read from the brightness of the phosphor screen, and the time and space from the position of the phosphor screen. 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.

3 Readout System*

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. 105 104 103 102 101 200 400 600 800 1000 Wavelength (nm) Radiant Sensitivity (µA/W) SPECIFICATIONS
