摘要： [Task] To provide a fundus oculi observation device capable of effectively performing dispersion compensation.[Means for Resolution] A fundus oculi observation device 1 functions as an optical image measurement device that splits a broadband light into a signal light LS and a reference light LR, superimposes the signal light LS propagated through a fundus oculi Ef and the reference light LR propagated through a reference mirror 174 to generate an interference light LC and forms an image of the fundus oculi Ef. The device 1 corrects the influence of dispersion of the reference light LR based on ocular information 212a, generates the interference light LC after the correction, detects this interference light LC, and forms an OCT image.

摘要： According to an embodiment, an attachment is attached to a main body part and has multiple bright points arranged in a ring. A calculation part calculates a first astigmatic axis angle based on an image obtained by using an imaging optical system to photograph the patient's eye while the multiple bright points are projected thereto. A storage stores the calculated first astigmatic axis angle and/or a second astigmatic axis angle measured before surgery. A mechanism changes the orientation of the main body part. A first input part inputs orientation information indicating the orientation of the main body part. A correction part corrects the first astigmatic axis angle and/or the second astigmatic axis angle based on the input orientation information. A display part displays the corrected first astigmatic axis angle and/or the corrected second astigmatic axis angle.

摘要： An optical imaging method is provided that can realize, at low cost, the extension of the imaging depth range. An optical imaging apparatus 400 is an apparatus that forms a tomographic image of an object using FD-OCT, and performs a scanning step, detection step and imaging step. In the scanning step, the object is scanned with a signal light while alternately changing the phase difference between the signal light and a reference light to two preset phase differences. In the detection step, interference light of the signal light passing through the object and the reference light is detected. In the imaging step, a tomographic image of the object is formed based on the detection results of a plurality of the interference lights sequentially obtained in the detection step according to the scanning.
