Abstract
In this article we present a detailed discussion of noise sources in Fourier Domain
Optical Coherence Tomography (FDOCT) setups. The performance of FDOCT with charge
coupled device (CCD) cameras is compared to current standard time domain OCT systems.
We describe how to measure sensitivity in the case of FDOCT and confirm the theoretically
obtained values. It is shown that FDOCT systems have a large sensitivity advantage
and allow for sensitivities well above 80dB, even in situations with low light levels
and high speed detection.
