摘要：

A new light source for swept-source optical coherence tomography (SS-OCT) is presented, namely, an external-cavity LD equipped with a KTN electro-optic deflector. The KTN deflector is unique in being very fast and simultaneously providing an appreciable deflection caused by injected carriers. Being free from mechanical resonance, the 1.3 mu m laser exhibits a scanning range of almost 80 nm up to 200 kHz with a +/- 400 V deflector driving voltage. Preliminary SS-OCT images of a human fingernail and finger skin have been obtained using the swept light source.
