INFORMATION OBTAINING APPARATUS AND METHOD FOR OBTAINING INFORMATION |
摘要 |
An information obtaining apparatus that obtains information regarding a subject includes a radiation unit configured to focus a terahertz wave having a plurality of different frequencies or a plurality of different beam diameters and radiate the terahertz wave onto the subject, a detection unit configured to detect the terahertz wave that has penetrated the subject or that has been reflected by the subject, a spectrum obtaining unit configured to obtain a spectrum of optical characteristics of the subject using a result of the detection performed by the detection unit, and a determination unit configured to determine a state of the subject on the basis of the spectrum obtained by the spectrum obtaining unit. The determination unit determines the state of the subject on the basis of a difference between a plurality of spectra obtained by the spectrum obtaining unit at a plurality of different positions in the subject. |
