Abstract
An OCT apparatus has a wavelength sweep light source changing a sweep frequency between a first sweep frequency and a second sweep frequency, an OCT optical system, an image processor, an FPN generation optical system generating a first FPN and a second FPN generated at a position separated from a zero delay position with respect to the first FPN, a detector, and a controller. The controller acquires first correction information based on the first FPN detected in a case of the first sweep frequency, and second correction information based on the second FPN detected in a case of the second sweep frequency. The controller applies the first correction information to an arithmetic process on a spectral interference signal obtained in the case of the first sweep frequency, and the second correction information to the arithmetic process on the spectral interference signal obtained in the case of the second sweep frequency.
