OPHTHALMIC IMAGING APPARATUS

PROBLEM TO BE SOLVED: To constitute an exit end of a fiber in such a manner as to reduce noise on a tomographic image due to scattering light on the exit end of the fiber.SOLUTION: An ophthalmic imaging apparatus for capturing a tomographic image of a subject's eye on the basis of light obtained by multiplexing return light from the subject's eye to which measuring light is applied and reference light corresponding to the measuring light, includes: a first fiber provided on an optical path of the reference light and including a light guide part for introducing the reference light; and a second fiber provided on an optical path of the measuring light and including a light guide part for introducing the measuring light. A diameter of the light guide part of at least one exit end of the first fiber and the second fiber is larger than a diameter of the light guide part at a position different from the exit end.SELECTED DRAWING: Figure 3 【課題】 ファイバの射出端で散乱した光に起因する断層像上のノイズが低減されるように、ファイバの射出端を構成すること。【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に基づいて、被検眼の断層画像を撮る眼科撮像装置が、参照光の光路に設けられ、参照光を導くための導光部を含む第１のファイバと、測定光の光路に設けられ、測定光を導くための導光部を含む第２のファイバと、を有し、第１のファイバと第２のファイバとの少なくとも１つの射出端の導光部の径は、射出端とは異なる位置の導光部の径よりも大きい。【選択図】 図３
