Abstract:

Optical coherence tomography (OCT) is an emerging imaging modality that is capable of providing noninvasive, subsurface optical imaging of biological tissues with micron-scale resolution. The operation of an OCT system is based on the principle of interferometer, which uses the low coherence interference between a reference and a signal beam derived from a broadband optical source. It can be used to generate slice images of three dimensional objects at a resolution level much greater than that currently available using MRI, CT scan, or

ultrasound scans. The goal of my work is to design and build a compact all-fiber Fourier domain OCT system based on a common-path interferometer configuration, to develop the software algorithms necessary to acquire cross-sectional biological tissue images at video rates (more than 30 frames per second per millimeter), to provide various scanning approaches.
