Abstract
Fourier Domain optical Coherence Tomography (FD-OCT) is used to obtain subsurface cross-sectional images
with micron level resolution by analyzing the interference pattern created by the mixing of light in a Michelson
Interferometer FD-OCT systems are able to obtain a direct measurement of the scattering amplitude along a
vertical axis within a bulk sample. One exposure provides the complete scattering profile from the surface into
the bulk of the sample; this measurement is commonly referred to as an A-scan. Fourier Domain optical
Coherence Tomography (FD-OCT) achieves greater sensitivity and higher imaging speed than time domain OCT
and has become a powerful tool for biomedical and material application
