| 1. A fundus observation device comprising:
a light source that outputs low-coherence light;
an interference light generation part configured to split said low-coherence light that has been output from said light source
into a signal light directed at the fundus oculi of an eye, and a reference light directed at a reference object, and configured
to superpose said signal light that has reached said fundus oculi and said reference light that has reached said reference
object, so as to generate an interference light;
a detection part configured to detect said generated interference light;
an image forming part configured to form image data of a tomographic image of said fundus oculi based on the results of detection
by said detection part;
an operation part; and
a drive part configured to move said reference object along the propagating direction of said reference light based on the
observation site of said fundus oculi specified via operation of said operation part.
