Diffuse optical tomography is an emerging biomedical imaging technique, due to its numerous advantages, such as low cost and non-ionizing radiation. In this work, we have developed a very simple setup, which included a single source - photodiode (SP)

The fundamental properties of free space optical channels in the ultraviolet (UV) spectral range between 200 and 280 nm are the enhanced scattering and the solar blind operation. Exploiting these properties, point-to-point links in a non-line-of-sigh

The exploitation of optical wireless communication channels in a non-line-of-sight regime is studied for pointto-point and networking configurations considering the use of light-emitting diodes. Two environments with different scattering center densi

One of the most critical parameters in free-space optical communications systems operating in a non-line-of-sight regime are the optical losses. In this Letter, we numerically calculate these losses taking into account the scattering effects using th

Proper thermal treatment of large core step index plastic optical fibers resulted in a transmission bandwidth improvement of > 35\% and optical loss decrease by approximately 7%. These improved properties remained after almost a year, with the fibers

In this letter, the code division multiple access discrete multitone (CDMA-DMT) modulation scheme is experimentally investigated for transmission over an intensity modulation direct-detection link of 100 m of 1-mm polymethyl methacrylate step-index p
