Patent ID: 7864331

Claim:
An optical tomograph, comprising: a light source unit for emitting a plurality of light beams, each of which has a continuous spectrum within discrete 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; 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: the plurality of measuring light beams are irradiated simultaneously on the same portion of the measurement target; the combining means combines the reflected light beam and the reference light beam for each of the light beams emitted from the light source unit; and the optical tomograph further comprises: an interference light separating means, for separating the interference light beam, formed by the combining means combining the reflected light beams and the reference light beams for each of the light beams emitted from the light source unit; and a plurality of interference light detecting means, for respectively detecting each of the interference light beams, separated by the interference light separating means.
