Synthesizing scanning-mode image formation in full-wave modelling of OCT (Conference Presentation)
Author(s): Callum M. Macdonald; Peter R. T. Munro

Paper Abstract

Models of OCT imaging systems which are rigorously based on Maxwells Equations offer significant benefits over approximate models. However, these full-wave propagation models require greater computational resources, particulary when dealing with large samples. In an effort to reduce this computational burden, we present a means of synthesizing scanning-mode OCT image formation using only a single simulation with plane-wave illumination incident on a 3D sample. An angular spectrum approach is used to synthesizes focussed illumination, and we investigate how the optical memory effect may permit this approach even in highly scattering samples. Demonstrations show that the required simulation time is reduced by an order of magnitude when synthesizing OCT B-scans compared with previous methods.
