Abstract

The embodiment of the invention discloses a high-speed spectrograph. The high-speed spectrograph comprises: a chromatic dispersion module for performing chromatic dispersion on probe light; a complementary metal oxide semiconductor COMS image sensor for detecting the probe light irradiated to the complementary metal oxide semiconductor COMS image sensor after the chromatic dispersion processing; and a control module electrically connected with the complementary metal oxide semiconductor COMS image sensor for controlling the complementary metal oxide semiconductor COMS image sensor to work andobtaining a spectrum of the probe light according to a detection signal output by the complementary metal oxide semiconductor COMS image sensor. The high-speed spectrograph in the technical scheme ofthe embodiment of the invention can work synchronously with a high repetition frequency laser to improve the measurement speed, accuracy and signal-to-noise ratio of an ultrafast laser spectrum.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a high-speed spectrometer. Background technique [0002] Ultrafast laser spectroscopy is to apply the theory and method of spectroscopy to explore the movement and change process of matter in the ultra-short limit time scale.
