Detection system and detection method thereof

Abstract

A detection system for detecting a bandwidth of an object to be tested is provided. The detection system includes a frequency-tunable laser module, a photoconductive semiconductor switch, and a digital acquisition system. The frequency-tunable laser module is configured to provide a first mixed frequency light and a second mixed frequency light, with a phase difference or a frequency difference between the first mixed frequency light and the second mixed frequency light. The photoconductive semiconductor switch is configured to receive the first mixed frequency light, the object to be tested is configured to receive the second mixed frequency light, and the photoconductive semiconductor switch and the object to be tested are coupled to output a mixed frequency signal. The digital acquisition system is configured to receive the mixed frequency signal to detect the bandwidth of the object to be tested. A detection method is also provided.
