Comparison of the performance of two depth-resolved optical imaging systems: Laminar optical tomography and spatially modulated imaging Conference Paper uri icon


  • The objective of this work is to compare quantitatively the imaging capabilities of a laminar optical tomography (LOT) system with those of a spatially modulated imaging (SMI) system. LOT is a three dimensional optical imaging technique that achieves depth sensitivity by measuring multiple-scattered light at different source-detector separations. The SMI method is based on spatially modulated illumination-detection patterns, which encode both optical properties and depth information. In this work, simulation studies are carried out at different noise levels, to obtain the figures of merit of tomographic reconstructions for both systems. Experiments on phantoms are performed to demonstrate the validity of the numerical results. © 2010 Copyright SPIE - The International Society for Optical Engineering.
