Sub-surface tomography with diffuse light has been investigated with a non-contact approach to characterize the performance of optical absorption and fluorescence imaging. Using both simulations and experimental studies, the reconstructed images of local sub-surface heterogeneities was demonstrated, using diffusion properties characteristic of near-infrared light in mammalian tissue. The result...

The presented paper is a techno-economic feasibility study to use solar energy as a renewable energy to power the Passive Optical Network (PON). This discussion focuses on the requirements and sources of power for the active components of optical access networks. To ensure continuous reduction of the carbon footprint while advancing towards purely passive optical networks, we have emphasized th...
