Reduction of periodic noise in Fourier domain optical coherence tomography images by frequency domain filtering
In Fourier domain optical coherence tomography (FDOCT) coherence noise is caused by interference of light waves back-reflected or scattered from different spots within a measuring depth or from optical components within the OCT system such as a bended optical fibre. This coherence noise appears as periodic stripe patterns along the axial direction in resulting images. Background subtraction and physical segmentation are used to degrade the periodic coherence noise in previous studies. Here we utilise a post-processing method by applying a frequency domain filter to reduce the periodic coherence noise. Even though the approach taken is a very simple one, it ...
