StreakKamera
StreakKamera, or streak camera, is a high-speed imaging instrument used to record the temporal evolution of light pulses by converting time into a spatial coordinate on a detector. It is commonly used in ultrafast optics to measure pulse shapes with picosecond or sub-picosecond resolution.
In operation, a light pulse illuminates a photocathode inside a vacuum tube, releasing electrons proportional to
The resulting streak image provides the temporal profile of the pulse. Time resolution depends on the sweep
Streak cameras are used in ultrafast laser spectroscopy, pump–probe experiments, plasma physics, accelerator physics, and telecommunications
Key components include the vacuum streak tube, photocathode, electron optics, fast sweep electrodes, and a readout
Developed in the mid-20th century, streak cameras remain a standard tool for time-resolved optical measurements. They
