ABSTRACT:
An optical tomographic apparatus is provided and includes a light source portion, an interferometer, and a signal processing portion. The light source portion including two low coherent light sources capable of simultaneously emitting light having wavelength bands different from each other. The emitted light is divided in two of a light flux irradiated to a subject by a probe and a light flux irradiated to reference mirrors that is divided by a dichroic mirror into light fluxes for respective wavelength bands. The reference light from the reference mirrors is combined with detected light from the subject to provide interference light. An optical detector detects the interference light for respective wavelength bands by a spectroscopic optical system, and a signal processing portion processes the detected light to provide optical tomographic images with regard to different portions of the subject for respective wavelength bands.
