Measuring the Delay Time of Starting a Streak Camera

A method for measuring the response time (dead time) of a streak camera (SC) for several sweep durations is presented. As a rule, the response time of an SC is measured only for the shortest sweep, which makes it difficult to synchronize the trigger pulse of an SC with a studied process when working...

Description
Summary:A method for measuring the response time (dead time) of a streak camera (SC) for several sweep durations is presented. As a rule, the response time of an SC is measured only for the shortest sweep, which makes it difficult to synchronize the trigger pulse of an SC with a studied process when working on other sweeps. The use of a laser diode with a front of at most 1 ns as a light-pulse marker significantly reduced the uncertainty of the moment when the pulse appears on the camera. In addition, the proposed method allows one to take all possible response delays into account, thus increasing the accuracy of the measurements, as well as to measure the duration of SC sweeps.
