  • Optical coherence tomography using active mode-locking fiber laser
    Patent number: 9207063
    Abstract: Discloses is an optical coherence tomography (OCT) which uses an active mode-locking fiber laser in order to obtain image information of a sample. An imaging device in accordance with an embodiment comprises: a light source unit; a light separation unit; a reference unit; a diagnostic unit; a light coupling unit; and a signal processing unit. The imaging device removes a high-priced variable filter which has mechanical restrictions by directly delivering a modulation signal to a light source unit, so it can overcome mechanical restrictions and reduce costs.
    Type: Grant
