Patent number: 11911108Abstract: A blood flow measuring unit of a blood flow measurement apparatus of an embodiment includes an optical system for applying an OCT scan to an eye fundus and obtains blood flow information based on data acquired by the OCT scan. A movement mechanism moves the optical system. A controller applies a first movement control to the movement mechanism to move the optical system in a first direction orthogonal to an optical axis of the optical system by a predetermined distance from the optical axis. A judging unit judges occurrence of vignetting based on a detection result of return light of light incident on the eye through the optical system after the first movement control. The controller applies a second movement control to the movement mechanism to further move the optical system based on a judgement result obtained by the judging unit.Type: GrantFiled: December 26, 2018Date of Patent: February 27, 2024Assignee: TOPCON CORPORATIONInventors: Jun Sakai, Shunsuke Nakamura, Kana Nishikawa, Masahiro Akiba
