摘要： The invention provides an optical image-measuring device that avoids long examination time and reduces some troublesome tasks. A fundus observation device 1 (optical image-measuring device) splits light that is output from a low-coherence light source 160 into a signal light LS directed toward the fundus oculi Ef and a reference light LR directed toward a reference mirror 174, and detects interference light LC that is generated by superimposing the signal light LS passing through the fundus oculi Ef and the reference light LR passing through the reference mirror 174 using a spectrometer 180 to form tomographic images of the fundus oculi Ef. Furthermore, the device comprises a reference mirror drive mechanism 243 shifting the reference mirror 174 toward the optical path direction of the reference light LR and a information storage part 225 storing the reference mirror 174 position information based on previous tomographic images. The controlling part 210 controls the reference mirror drive mechanism 243 so that the reference mirror 174 shifts into a position based on reference mirror position information related to the eye to be examined E that is stored in the information storage part 225.

摘要： Highly reliable technology is provided with the capable of forming three-dimensional images of fundus oculi. The image forming part 220 of a computational control unit 200 forms images of the surface of fundus oculi Ef based on results of detecting fundus oculi catoptric light of light illuminated by a fundus camera unit 1A, in addition to forming tomographic images of the fundus oculi Ef based on results of detecting interference light LC from the OCT unit 150. The controlling part 210 synchronizes the timing of detecting fundus oculi catoptric light of light illuminated by the fundus camera unit 1A with the timing of detecting interference light LC from the OCT unit 150. The correction processing part 240 corrects the image positions of the tomographic images based on results of detecting interference light LC from the OCT unit 150 on the basis of two-dimensional images based on the results of detecting fundus oculi catoptric light of light illuminated from the fundus camera unit 1A. The image processing part 230 forms three-dimensional images of fundus oculi Ef based on tomographic images for which the image positions have been corrected.
