摘要： A fundus oculi observation device 1 splits a low-coherence light L0 into a signal light LS and a reference light LR, generates an interference light LC from the signal light LS propagated through an eye E and the reference light LR propagated through a reference mirror 174 to detect the interference light LC and, based on the result of the detection, forms a tomographic image of a fundus oculi Ef. The device 1 includes a scan unit 141 configured to scan with the signal light LS, and an LCD and optical system that present a fixation target. The device 1 acquires an image of the fundus oculi Ef in a state that scan a fixation target is presented while scanning with the signal light LS, and based on the image, determines whether fixation is proper or not.

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 device 1 is an OCT device that splits a low-coherence light L0 into a signal light LS and a reference light LR, detects an interference light LC obtained by superimposing the signal light LS propagated through an eye E and the reference light LR propagated through a reference mirror 174, and forms an image of an fundus oculi Ef. The device 1 has a scan unit 141 that scans the eye E with the signal light LS. When a cross-section position is designated in an fundus oculi image Ef', the device 1 repetitively scans with the signal light LS 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 240A. An operator can observe the tomographic motion image to designate the range and timing for measurement of a tomographic still image.
