OPTICAL TOMOGRAPHY DEVICE

摘要

An optical tomography device 1 is provided as one capable of obtaining tomographic information of a measuring object with higher accuracy. In the optical tomography device 1, numerical apertures of reception fibers 12, 13 are different from each other. Therefore, the device has a configuration wherein the reception fibers 12, 13 receive two kinds of respective light beams with different solid angle distributions, whereby the device can also obtain angular information, in addition to intensity information of light emerging from a measuring object 100. As a result, the accuracy is enhanced for an analysis about the tomographic information of the measuring object.

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, and wherein the plurality of optical fibers have two or more different numerical apertures.
