摘要

PROBLEM TO BE SOLVED: To provide an OCT apparatus which can achieve higher image quality of an OCT image and improvement of SNR without using a complicated device.;SOLUTION: An OCT device includes: a first light source unit which changes wavelength of light to be emitted; a second light source unit which changes wavelength of light to be emitted over a wavelength range different from a wavelength range of the first light source unit, and partially overlapping the wavelength range of the first light source part; a signal generation unit which receives the light to be emitted from the first and second light source units, and transmits signals at equal wave number intervals; an interference optical system which splits the light to be emitted from the first and second light source units into illumination light to be illuminated on an object and reference light and generates interference light; a light detection unit which receives first and second interference light to be obtained by the first and second light source units; and an information acquisition unit which acquires a tomographic image of the object by connecting temporal waveforms of intensities of the first and second interference light. The information acquisition unit connects the temporal waveforms of the intensities of the first and second interference light based on the signals generated from the signal generation unit.;COPYRIGHT: (C)2014,JPO&INPIT
