Provided is an ophthalmic imaging apparatus, including: a combining unit combining return light obtained by irradiating an eye to be inspected with the measuring light, and the reference light to obtain interference light; an adjusting unit adjusting a polarization state of at least one of the return light or the reference light; and an acquiring unit acquiring information indicating depolarization of the eye using information about a difference between intensity of first interference light obtained under a first polarization state and intensity of second interference light obtained under a second polarization state, the first polarization state being in which the adjustment is performed so that polarization states of the return light and of the reference light match with each other, the second polarization state being in which the adjustment is performed so that the polarization states of the return light and of the reference light differ from each other.
An ophthalmic imaging apparatus, comprising:
A method of controlling an ophthalmic imaging apparatus, the ophthalmic imaging apparatus including a combining unit, which is configured to combine, after light emitted from a light source is divided into measuring light and reference light, (a) sample light, which is returned from an eye to be inspected irradiated with the measuring light, and (b) the reference light, to obtain interference light, the method comprising:
