Paper Abstract

High scattering in biological turbid media limits the applicability of optical imaging techniques, such as optical coherence tomography (OCT). Accurate and robust simulations are required due to the complexity of optical wave propagation in these tissues. Recent computational simulations make use of finite-difference time-domain (FDTD) method to exactly solve the scattered electromagnetic field distribution. We propose a method to isolate and selectively remove energy from portions of the scattered field in these simulations. This technique will involve placing an absorber in the medium that consists of convolutional perfectly matched layers (CPML). The performance of the absorber as an optical target is analyzed.
