Abstract:
Provided are an apparatus and a method which enable acquisition of a temporal waveform of a propagating terahertz wave by changing a propagation velocity of the terahertz wave. A waveform information acquisition apparatus includes a generation portion for generating a terahertz wave, a propagation portion for allowing the terahertz wave generated by the generation portion to propagate therethrough, a detection portion for detecting waveform information of the terahertz wave, a first delay portion for changing a propagation velocity of the terahertz wave, and a control portion for controlling the first delay portion to change the propagation velocity of the terahertz wave in the propagation portion, and acquires information regarding the temporal waveform of the terahertz wave detected by the detection portion.
