Abstract:
1. An optical tomography device comprising: a light source; an irradiation fiber for irradiating a measuring object with light from the light source; a receiving fiber for receiving light emerging from the measuring object in conjunction with irradiation with the light from the irradiation fiber; a detection unit for detecting an intensity of the light received from the receiving fiber; and an analysis unit for obtaining an optical characteristic value of an interior of the measuring object, based on the intensity of the light detected by the detection unit, wherein at least one of the irradiation fiber and the receiving fiber is a bundle in which a plurality of optical fibers are bundled together, wherein the plurality of optical fibers have two or more different numerical apertures, and wherein the analysis unit obtains an average of the optical characteristic value in the interior of the measuring object, and a distribution of the optical characteristic value in the interior of the measuring object in order to determine a structure of the interior of the measuring object from the distribution of the optical characteristic value.
