Abstract

The invention discloses a system and method for measuring the radiation waveform of a terahertz pulse radiator, which relate to the technical field of radiation wave measurement, and aim to solve theproblem that a conventional radiation waveform measurement method cannot meet the measurement requirements of the radiation waveform of the terahertz pulse radiator. The device comprises a laser repetition frequency locking module for locking the output repetition frequency of a master fiber femtosecond laser and a slave fiber femtosecond laser according to a time base reference signal, and sending the repetition frequency difference as a trigger signal to acquisition equipment, a synchronization module which synchronizes the output signal to the repetition frequency of the slave fiber femtosecond laser and provides a trigger signal for the tested terahertz pulse radiator, so that the repetition frequency of the radiation pulse of the tested terahertz pulse radiator is the same as the repetition frequency of the trigger signal, a terahertz detector which generates photon-generated carriers under the excitation of the master fiber femtosecond laser and generates current under the actionof the terahertz pulse of the measured radiation, and acquisition equipment which is used for acquiring the current signal output by the terahertz detector.

Description

technical field [0001] The invention relates to the technical field of radiation wave measurement, in particular to a measurement system and a measurement method for the radiation waveform of a terahertz pulse radiator. Background technique [0002] The pulse radiator is a generator that radiates pulse signals to space through its own integrated antenna, and is widely used in pulse wireless synchronization, pulse radar, pulse imaging and other fields. In order to optimize the design of the pulsed radiator, improve its performance, and ensure its application, it is necessary to accurately measure the performance of the pulsed radiator. The key performance indicators of the pulse radiator mainly include pulse amplitude, rise time, half-width, bandwidth, etc. In order to accurately measure these indicators, it is necessary to accurately measure the pulse signal waveform radiated by the pulse radiator. Therefore, the measurement of the pulse radiator radiation waveform is very ...
