ABSTRACT:
To provide an apparatus capable obtaining a temporal waveform of terahertz waves transmitted through or reflected by a sample in a set region. A delay unit is configured to change a timing at which the detection unit detects terahertz waves transmitted through or reflected by a sample, which is originated from terahertz waves generated by a generation unit. A waveform obtaining unit is configured to obtain a temporal waveform of the transmitted terahertz waves which are obtained by using the delay unit. The delay unit, of which more than one may be used, is controlled so that the detection unit detects the transmitted terahertz waves in an area related to the temporal waveform set on the basis of information related to the sample that is pre-stored in the storage unit. Then, a temporal waveform of the transmitted terahertz waves in the area is obtained.
