FUNDUS OCULI OBSERVING DEVICE
First Claim
Patent Images
1. A fundus oculi observing device, comprising:
- an optical system configured to split a low-coherence light into a signal light and a reference light and make the signal light propagated through a fundus oculi of an eye and the reference light propagated through a reference object interfere with each other to generate an interference light;
a detector configured to detect the generated interference light and generate detection signals;
a scanner configured to perform a scan of a target position with the signal light on the fundus oculi;
an image forming part configured to form a tomographic image of the fundus oculi based on the detection signals generated during the scan;
a specifying part configured to specify a characteristic site of the fundus oculi depicted in the formed tomographic image; and
a controller configured to, based on a position of the specified characteristic site within a frame of the tomographic image, control the scanner to change the target position of the signal light so that the characteristic site is depicted in a predetermined position within the frame.

Abstract
A fundus oculi observing device 1 specifies a characteristic site of a fundus oculi Ef depicted in tomographic images of the fundus oculi Ef and, based on the position of the characteristic site within frames FH and FV of the tomographic images, changes a target position of a signal light LS so that the characteristic site is depicted in the center positions within the frames FH and FV and executes a main measurement, thereby forming a tomographic image and/or a three-dimensional image of the fundus oculi Ef.
