Abstract

Optical coherence tomography (OCT) is a new biomedical imaging technique in resent year. It has some good qualities, such as non-ionizing radiation, non-invasive, high resolution and sensitivity. High-speed OCT imaging is very important for obtaining the cross-sectional images of the internal microstructure of living tissue. Increasing the imaging speed can produce imaging real time. To study high speed OCT, a new method of OCT imaging technique has been designed in this paper--replacing the point-focus mode with line-focus mode in the sample arm. Cylindrical lens can be used for focusing the incident light into a line in the sample. And a 2D OCT imaging can be obtained in one dimension scanning. In the paper we analyze the interference principle of line-focus imaging mode.
