INFORMATION ACQUIRING APPARATUS AND INFORMATION ACQUIRING METHOD FOR ACQUIRING INFORMATION ON SPECIMEN BY USING TERAHERTZ WAVE

摘要

An information acquiring apparatus that acquires information on a specimen by applying terahertz wave to the specimen through a plate-like member, the specimen being provided between a reflecting member having a reflecting surface and the plate-like member. The apparatus includes an applying unit that applies the terahertz wave to the specimen, a detecting unit that detects the terahertz wave reflected from the specimen, and an information acquiring unit that acquires the information on the specimen by using temporal waveforms acquired from a result of detection performed by the detecting unit, the information acquiring unit using at least a temporal waveform representing a portion of the terahertz wave that is reflected by an interface between the plate-like member and the specimen and a temporal waveform representing a portion of the terahertz wave that is reflected by an interface between the specimen and the reflecting surface of the reflecting member.
