OPHTHALMIC DEVICE, METHOD FOR CONTROLLING OPHTHALMIC DEVICE, AND PROGRAM

An ophthalmic device including an interference optical system that detects interference light between signal light obtained by scanning an examined eye with light from a light source and reference light configured from light divided from the light source, an adjustment section that is disposed on an optical path of at least one out of the signal light or the reference light, and that adjusts a polarization state of light propagating along the at least one optical path such that a polarization state of the signal light is the same as the polarization state of the reference light, and a control section that controls the adjustment section according to a scan angle scanned on the examined eye.
