High-speed optical coherence tomography based on line scanning

Optical coherence tomography (OCT) based on the theory of Michelson interferometer is a novel imaging technique with high resolution and performs non-invasive. The images of traditional OCT system can be obtained through pointscanning which its scanning speed is slow, and this limits the real time measurement of the system. This paper introduces a new imaging technique of OCT system with high speed, using line-scanning method instead of pointscanning method. The new method can increase the scanning speed and can realize real time measurement, which provide a fundamental technique for the high-speed imaging.
