Provided are an optical tomographic imaging apparatus and an imaging method for an optical tomographic image, in which high measurement sensitivity and high lateral resolution of a specific portion of an object may be obtained with a simple structure. The optical tomographic imaging apparatus of a Fourier-domain method includes: an optical path length adjustment portion for adjusting an optical path length of the reference beam; a position adjustment portion for adjusting a position of a focusing device for focusing the measuring beam onto the object; and a drive control portion for controlling drive of the optical path length adjustment portion and the position adjustment portion. The drive control portion is controlled based on information from a layer constituting a cross section from cross section information that is obtained in advance for a portion to be imaged of the object.
An optical tomographic imaging apparatus acquiring tomographic image of an object based on a combined light beam of a return beam from the object irradiated with a measuring beam and a reference beam corresponding to the measuring beam, comprising:
