Abstract
An OCT apparatus includes, in addition to a first light source that changes a wavelength of light that is emitted, a second light source that emits light having a particular wavelength. The OCT apparatus is formed so that, when light having the particular wavelength is emitted from the first light source, the light emitted from the second light source is detected by a second optical detector.
