ABSTRACT:
Light is split into a signal light LS directed toward the fundus oculi Ef and a reference light LR directed toward a reference mirror174, and interference light LC generated by superimposing the signal light LS passing through the fundus oculi Ef and the reference light LR passing through the reference mirror174using a spectrometer180is detected to form tomographic images. A reference mirror drive mechanism243shifts the reference mirror174toward the optical path direction of the reference light LR and an information storage part225storing the reference mirror174position information based on previous tomographic images. The controlling part210controls the reference mirror drive mechanism243so that the reference mirror174shifts into a position based on reference mirror position information stored in the information storage part225.
