PROBLEM TO BE SOLVED: To efficiently perform the rendering of both a vascular structure and an anatomical structure and lesion of a subject eye.SOLUTION: Provided is an ophthalmic imaging apparatus, including: detection means 141, 142 for detecting light beams of different polarization obtained by splitting light obtained by multiplexing return light from a subject eye irradiated with measurement light and reference light corresponding to the measurement light scan means 114 for scanning the subject eye with the measurement light and control means for controlling the scan means such that the same site of the subject eye is scanned with the measurement light by a plurality of times. The ophthalmic imaging apparatus acquires motion contrast information in the subject eye using light beams of different polarization detected under control of the control means. When different sites of the subject eye corresponding to a movement of the subject eye are scanned with the measurement light under control of the control means, the ophthalmic imaging apparatus acquires information indicating the depolarization of the subject eye using light beams of different polarization detected in regions corresponding to between the different sites in the scan direction of the scan means and the depth direction of the subject eye.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】被検眼の血管構造の描出と解剖学的構造・病変の描出との両方を効率的に行うこと。【解決手段】測定光を照射した被検眼からの戻り光と測定光に対応する参照光とを合波して得た光を分割して得た互いに異なる偏光の光を検出する検出手段141,142と、被検眼に対して測定光を走査する走査手段114と、被検眼の同一位置に対して測定光を複数回走査するように走査手段を制御する制御手段と、を有する眼科撮影装置は、制御手段による制御下において検出された互いに異なる偏光の光を用いて、被検眼におけるモーションコントラスト情報を取得し、制御手段による制御下において被検眼の動きに対応する被検眼の異なる位置で測定光が走査された場合に、走査手段による走査方向及び被検眼の深さ方向における上記異なる位置の間で対応する領域の検出された互いに異なる偏光の光を用いて、被検眼の偏光解消性を示す情報を取得する。【選択図】図2
