摘要： An OCT technique that permits tomographic observation of biological body parts that are difficult to restrain, and also provides a tomographic observation technique for the observation of a constrainable part that does not require constraint and thus removes a burden on the biological body. A wavelength-tunable light generator (wavelength-tunable light source) is employed as the light source of the optical coherence tomography device. The wavelength-tunable light generator has a wave number tunable range width of at least 4.7×10−2 μm−1 and an emitted-light frequency width of no more than 13 GHz, for example, and is capable of changing the wave number stepwise at wave number intervals of no more than 3.1×10−4 μm−1 and time intervals of no more than 530 μs.

摘要： There is provided an optical coherent tomography device capable of enlarging a measurement range by removing the affect of a folded image. The device includes an optical phase modulator (14) enabling operation amplifiers (17, 18) and a calculation control device (21) to measure a first intensity as a cosine function for the wave number and a second intensity as a sine function or inverse code function for the wave number from the intensity of the output light multiplexed by a third coupler (16). The calculation control device (21) is based on a first intensity set and a second intensity set of the output light by the optical phase modulator (14) measured by the operation amplifiers (17, 18) and the like, so as to suppress generation of a folded image and identify reflection or a backscattering position and a reflection intensity or a back scattering intensity of the measurement light for the irradiation direction of the measurement light in the measurement object.

摘要： An optical measuring instrument which enables measurement of necessary data in a short period of time and uses a light with a short coherence length. In this instrument, such a light emitted from a light source is divided into a measurement light and a plurality of reference lights. The plurality of reference lights are processed by different frequency modulations, and then multiplexed with a light reflected from a measurement object irradiated by the measurement light. On the basis of an output of a photoelectric converter for detecting the level of the multiplexed light and the frequency of each reference light, optical characteristic data related to a plurality of measurement points are calculated.
