Abstract: A fundus oculi observation device 1 divides a low-coherence light L0 into a signal light LS and a reference light LR, superimposes the signal light LS propagated through a a fundus oculi Ef and the reference light LR propagated through a reference mirror 174 to generate and detect an interference light LC, and forms an OCT image of the fundus oculi Ef based on the result of the detection. The fundus oculi observation device 1 scans with the signal light LS while changing a scan interval when performing a series of scans with the signal light LS. Thus, it is possible to acquire a highly accurate image at small scan intervals from an attention site, and it is possible to reduce a scanning time by scanning at large intervals in other sites. Accordingly, it is possible to rapidly acquire a highly accurate image of an attention site.

Abstract: A device is an OCT device that splits a low-coherence light into a signal light and a reference light, detects an interference light obtained by superimposing the signal light propagated through an eye and the reference light propagated through a reference mirror, and forms an image of an fundus oculi. The device has a scan unit that scans the eye with the signal light. When a cross-section position is designated in an fundus oculi image, the device repetitively scans with the signal light along each cross-section position to repeatedly forms tomographic images at each cross-section position, thereby displaying a tomographic motion image at each cross-section position on a display. An operator can observe the tomographic motion image to designate the range and timing for measurement of a tomographic still image.

Abstract: 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).
