Time-domain spectroscopy and time-domain spectroscopic analysis system

A time-domain spectroscopy, comprising:

• a splitter for splitting pulsed light entered;
• a variable delayer for delaying timing of a first part of the pulsed light split by the splitter;
• an electromagnetic wave generator for converting a second part of the pulsed light split by the splitter into an electromagnetic wave;
• a detector for detecting measurement data from a pulse having passed through a measurement object subjected to the electromagnetic wave emitted from the electromagnetic wave generator, and the pulse outputted from the variable delayer;
• and
• a comparator for detecting a phase difference between the pulsed light before being entered into the electromagnetic wave generator and the pulsed light outputted from the variable delayer,
• wherein data obtained by the comparator and the measurement data are used to obtain a measurement result of the measurement object.
