Abstract

Realistic modelling of image formation in optical coherence tomography, which models light propagation in the sample using Maxwell’s equations, is useful for applications such as training researchers and clinicians, image interpretation and technique development. Such models, however, require specialised knowledge of numerical techniques for solving Maxwell’s equations, and for modelling optical systems. Here I present a freely available, open source package, aimed at making such simulations accessible to researchers throughout the optical coherence tomography community. Time Domain Maxwell Solver (TDMS) is based on the finite difference time domain (FDTD) and pseudo spectral time domain (PSTD) methods, and includes functionallity required to model optical systems typically found in OCT systems. TDMS includes several use case examples aimed at making it easy for users with limited background in simulation to use the package.
