1. Optical coherence tomography has become an important tool for medical imaging and increasingly for quantitative metrological applications. As a consequence detection sensitivity is highly valued. In this paper, we introduce a novel post-processing technique for digitally stabilizing and spectrally averaging optical coherence tomography datasets in order to enhance detection sensitivity. We demonstrate sensitivity gains of 18 dB when the algorithm is applied to data from a high-speed Fourier domain system. (Read Full Article)
