<p><P>PROBLEM TO BE SOLVED: To provide an apparatus and a method for acquiring a temporal waveform of a propagating terahertz wave by changing a propagation velocity of the terahertz wave. <P>SOLUTION: This waveform information acquisition apparatus has a generating part for generating a terahertz wave; a propagating part for propagating the terahertz wave generated by the generating part; a detecting part for detecting waveform information of the terahertz wave; a first delay part for changing the propagation velocity of the terahertz wave; and a control part for controlling the first delay part to change the propagation velocity of the terahertz wave in the propagating part. The waveform information acquisition apparatus acquires information on the temporal waveform of the terahertz wave detected by the detecting part. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
