  • Fundus oculi observation device and program controlling the same
    Patent number: 8403482
    Abstract: [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.
