    摘要： A fundus observation device is provided capable of capturing both images of the surface of the fundus oculi and tomographic images of the fundus oculi, and capable of preventing alignment indicators from being reflected in the image of the fundus oculi. Image forming part 220 operates to form surface images based on results of detecting the reflection light by the fundus oculi Ef of the illumination light obtained from a fundus camera unit 1A, and operates to form tomographic images based on results of detecting interference light LC by the OCT unit 150. The fundus camera unit comprises alignment optical systems 110A and 190A, which project an alignment indicator. Detection timing controlling part 210B controls a fundus camera unit 1A and makes it detect the illumination light substantially simultaneously with detection of the interference light. Before the interference light LC and illumination light are substantially simultaneously detected, the alignment controlling part 210 controls the alignment optical system 110A and 190A and terminates the projection of the alignment light indicator. Correction processing part 225 corrects the image position of tomographic images using the surface images obtained substantially simultaneously.

    摘要： The ophthalmologic apparatus 1 splits low coherence light LO into a signal light LS and a reference light LR, the interference light LC being generated by having the signal light LS overlap with the reference light LR, and detects this interference light LC. In addition, the apparatus comprises an optical alignment system 190A for performing the alignment of an optical system forming the signal light path to the eye E. An intraocular distance calculator 214 determines the distance between the position where the signal light LS has been introduced onto the eye E and the position where the signal light LS has been reflected by the fundus oculi E based on length of the optical path of the signal light, the length of the optical path of the reference signal light, the working distance after alignment, and the detection signal output by the CCD 184 (or signal intensity data).
