An optical tomography system for obtaining a tomographic image of an object to be measured includes a light source unit which emits low coherence light. The low coherence light emitted from the light source unit is divided into measuring light and reference light. The reflected light from the object when the measuring light is projected onto the object and the reference light are multiplexed. The interference light of the reflected light and the reference light which have been multiplexed is detected, and a tomographic image information of the object is obtained by carrying out frequency-analysis on the detected interference light. A first detecting mode in which the interference light is detected at a first wavelength resolution and the interference light is detected at a second wavelength resolution higher than the first wavelength resolution are switched.
