PROBLEM TO BE SOLVED: To provide an optical coherence tomography device having an improved longitudinal resolution.SOLUTION: The optical coherence tomography device comprises: division means which divides light emitted from a light source into measurement light and reference light and an optical member which corrects the spectral characteristic of one of the light emitted from the light source, the measurement light, and the reference light so as to widen the wavelength band of interference light between the return light from a subject eye irradiated with the measurement light and the reference light.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】 縦分解能が向上された光干渉断層撮像装置を提供すること。【解決手段】 光干渉断層撮像装置は、光源からの光を測定光と参照光とに分割する分割手段と、測定光を照射した被検眼からの戻り光と参照光との干渉光の波長帯域が広くなるように、光源からの光と測定光と参照光との少なくとも一つの分光特性を補正する光学部材と、を有する。【選択図】 図4
