    摘要: An optical image measurement device has: an interference-light generator (150) configured to generate an interference light (LC) by splitting a low-coherence light into a signal light (LS) and a reference light (LR) and superimposing the signal light having passed through an eye (E) and the reference light having passed through a reference object (174); a detector (184) configured to detect the generated interference light; and a scanner (141) configured to scan a projection position of the signal light on the eye, and the optical image measurement device is configured to form an image of the eye based on a result of detection by the detector. The optical image measurement device comprises a projector (140) configured to project fixation information for fixing the eye onto a fundus oculi (EF) of the eye when the scanner scans with the signal light.

    摘要: A LCD (140) is provided for displaying an internal fixation target for fixating an eye (E). A projection optical system (a part of an imaging optical system (120)) is provided for projecting the displayed internal fixation target onto the a fundus oculi (Ef). An image forming part (220) is provided for forming 2-dimensional images (images of fundus oculi) (Ef') of the surface of fundus oculi (Ef). A display part (240A) is provided for displaying images of fundus oculi (Ef). An operation part (240B) is provided for specifying the position of the displayed images of fundus oculi (Ef'). A main controller (211) is provided for changing the projection position of the internal fixation target on the fundus oculi by changing the display position of the fixation target displayed on the LCD (140) based on the specified position specified using the operation part (240B). The image forming part (220) forms tomographic images of the fundus oculi (Ef) with the internal fixation target projected.
