Wavefront control through multi-layer scattering media using single-pixel detector for high-PSNR optical transmission

Abstract

We propose a new approach for optical analog-signal transmission through multi-layer scattering media using single-pixel detector to achieve high peak signal-to-noise ratio (PSNR), and analog signals can be experimentally received with high PSNR through multi-layer scattering media. The proposed approach, experimental observation and optical experimental results are presented that intensity of the propagating wave recorded by using single-pixel detector can directly produce high-PSNR signals through multi-layer scattering media using coherent light source at the receiving end. In our optical experiments, high-PSNR optical transmission is realized in different wave propagation environments, e.g., multi-layer scattering media. The observed phenomenon and the proposed approach provide a new and interesting insight about optical analog-signal transmission through multi-layer scattering media.
