Abstract

The invention provides a synchronous scanning streak camera temporal resolution measuring device and method, and aims at solving the problem that the confidence coefficient of a conventional testing method is low. The synchronous scanning streak camera temporal resolution measuring device comprises a femto second laser device, a first spectroscope, a fast recovery diode, a beam expanding lens, a second spectroscope, a first reflector, a second reflector and a length-measuring interferometer. The first spectroscope is arranged on the output light path of the femto second laser device, the fast recovery diode is arranged on the transmission light path of the first spectroscope, the beam expanding lens is arranged on the reflection light path of the first spectroscope, the second spectroscope is arranged on the output light path of the beam expanding lens, the first reflector is arranged on the transmission light path of the second spectroscope, the second reflector is arranged on the reflection light path of the second spectroscope, the length-measuring interferometer is arranged right behind the second reflector and used for measuring the moving distance of the second reflector in the light path direction of the second reflector, and the second reflector is a double-faced reflector. According to the invention, high-precision measurement of the resolution of a high-temporal resolution synchronous scanning streak camera is achieved.

Description

technical field [0001] The invention belongs to the field of photoelectric detection, and relates to a measuring device and a testing method for the time resolution of a streak camera, in particular to a measuring device and a testing method for a synchronously scanning streak camera. Background technique [0002] Streak camera is the only high-end scientific measurement and diagnostic instrument with both ultra-high time resolution and high spatial resolution. It is a necessary means to realize the detection of microscopic and ultra-fast processes, and it is of great significance for basic frontier scientific research and major original innovation research. The synchronous scanning streak camera is a kind of streak camera, which can test the instantaneous change of weak periodic light field.
