Abstract
In an embodiment, a computer, which generates tomographic images based on spectral interference signals detected by a light detectorfrom overlaid reference light emitted by a swept-source type light sourceof a SS-OCT, split, and then reflected by a fixed reference mirroron one hand and object light reflected by an object to be measuredon the other, is caused to function to apply rough correction using a first correction means and then apply detailed correction using a second correction means, to stabilize the phases of the SS-OCT. The phases can be stabilized by eliminating, without adding any expensive, complex hardware, the jitter between the wavelength scanning of a light source of SS-OCT and the timing of collecting the scan data with the light detector as spectral interference signals.
