摘要： 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.

摘要： A fundus oculi observation device 1 can form a near-infrared motion image and a color image (still image) of a fundus oculi Ef. The device 1 specifies an image region within the near-infrared motion image corresponding to a region of interest within the color image while the near-infrared motion image is being formed. The device 1 scans with a signal light LS based on the specified image region, thereby forming a tomographic image along the scanning line. According to the device 1, it is possible to determine a region of interest within a still image having a comparatively high image quality, specify the image region within the motion image corresponding to this region of interest, set a measurement site for the tomographic image.

摘要： 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.
