Provided is a terahertz time-domain spectrometer, comprising: a laser (1); a first light splitter (3), which splits laser light into pump light and detection light; a time delay device (4), which is used for adjusting a time delay of the detection light with respect to the pump light; a second light splitter (8), which is used for splitting the detection light into first detection light and second detection light; a first terahertz antenna (11), which emits a first terahertz wave under the action of the pump light, wherein the first terahertz antenna (11) is also used for detecting a terahertz wave, reflected by a sample to be detected (15), of the first terahertz wave, and the first detection light; a second terahertz antenna (12), which is used for detecting a terahertz wave, transmitted by the sample to be detected (15), of the first terahertz wave, and the second detection light; a first processing module (13), which is used for analyzing a spectral signal detected by the first terahertz ...
