Abstract:
1. An optical tomography system for obtaining a tomographic image of an object to be measured comprising a light source unit which emits light while sweeping the wavelength thereof at predetermined periods, a light dividing means which divides the light emitted from the light source unit into measuring light and reference light, a multiplexing means which multiplexes the reflected light from the object when the measuring light divided by the light dividing means is projected onto the object and the reference light, an interference light detecting means which detects interference light of the reflected light and the reference light which have been multiplexed by the multiplexing means, and a tomographic information obtaining means which obtains a tomographic information of the object by carrying out frequency-analysis on the interference light detected by the interference light detecting means, a detecting mode control means which switches between a first detecting mode in which the interference light is detected at a first wavelength resolution and a second detecting mode in which the interference light is detected at a second wavelength resolution higher than the first wavelength resolution being provided.
