In an optical tomography system, interference light is detected and a controller switches between a measurement initiating position adjusting mode and a tomographic image obtaining mode. The interference light is detected by an interference light detecting system including a spectral system which spectrally divides the interference light, a first optical system formed of a plurality of photo-sensors which detects the interference light by the wavelength band and a second optical system detecting a part interference light at a wavelength band which is a part of the whole wavelength band of the spectrally divided interference light in the measurement initiating position adjusting mode. The controller controls the interference light detecting system to detect the interference light with the first optical system in the image obtaining mode and with the second optical system in the measurement initiating position adjusting mode.
