Patent ID: 8403482

Claim:
A fundus oculi observation device that splits light from a light source into a signal light and a reference light, superimposes the signal light propagated through a fundus oculi and the reference light propagated through a reference object to generate an interference light, and forms an image of the fundus oculi based on a result of detection of the interference light, the fundus oculi observation device comprising: a storage configured to store ocular information including axial length information; and an optical element for dispersion compensation placed on the light path of the reference light; and a corrector configured to obtain a correction amount of the optical element to correct an influence of dispersion exerted on the signal light and/or the reference light, based on the ocular information, so as to correct a position of the optical element based on the obtained correction amount, wherein an interference light based on the light from the light source is generated after the correction, the inference light is detected, and an image of the fundus oculi of the eye is formed based on a result of the detection, wherein the corrector is configured to obtain an equation between a light path length of the signal light and a light path length of the reference light based on the ocular information, and to correct the influence of dispersion based on the equation, and wherein the ocular information includes refraction index information of an ocular optical system; and the corrector is configured to calculate the light path length of the signal light based on the axial length information, the refraction index information and a light path length from a split position of the light of the light source to the eye, and to obtain an equation of the calculated light path length of the signal light and the light path length of the reference light, as the equation.
