Fundus imaging using DCRA toward large eyebox

2019. 11. 15

We propose a novel fundus imaging system using a dihedral corner reflector array (DCRA) that is an optical component to work as a lens but does not have a focal length or an optical axis. As a sensing application, we use a DCRA for setting a virtual camera in/on an eyeball to capture a fundus. The proposed system has three features; (1) robust to eye movement, (2) wavelength- independent, (3) a simple optical system. The proposed system has a possibility to be applied to preventive medicine for households that can be used in daily life.

二面角コーナーリフレクターアレイ(DCRA)を使用した新しい眼底撮影法を提案します。DCRAには、光源を面対称位置に結像させる機能があります。この機能を用いて、DCRAを使用して眼球内または眼球上に仮想カメラを生成し、眼底にある網膜を撮影します。提案された方法では、目の動きに頑健な、波長非依存性を持つ簡易な光学系を実現します。
