Abstract:
1. An optical tomograph, comprising: a light source unit for simultaneously emitting a plurality of light beams, the wavelengths of each of which are swept within different predetermined wavelength bands respectively; light dividing means, for dividing each of the light beams emitted from the light source unit into a measuring light beam and a reference light beam; combining means, for combining reflected light beams, which are the measuring light beams reflected by a measurement target when the measuring light beams are irradiated thereon, with the reference light beams divided by the light dividing means, for each of the light beams emitted by the light source unit; interference light detecting means, for detecting an interference light beam, which is formed by the reflected light beam and the reference light beam being combined by the combining means, for each of the light beams as an interference signal; and tomographic image processing means, for generating a tomographic image of the measurement target employing the plurality of interference signals detected by the interference light detecting means, wherein: a separate light dividing means and a separate combining means are provided for each of the light beams emitted from the light source unit.
