PURPOSE: An optical coherence tomography system using an active mode locking laser is provided to connect a plurality of light sources, which are a laser resonator, in a row and to input modulated signals to a light transmitting device, thereby enlarging a broadband and improving output efficiency. CONSTITUTION: An optical coherence tomography system(1) using an active mode locking laser comprises a modulated signal generator, light sources(10), a beam splitter(20), a reference unit(30), an analysis unit(40), a photo coupler(50), and a signal processor(60). The modulated signal generator generates signals of a specific waveform, which are periodically changed, and generates modulated signals in which central frequencies are changed by the generated signals. The light source emits lights in which the central frequencies are periodically changed by the modulated signals transmitted from the modulated signal generator through the resonator.
