Outline of Final Research Achievements

The purpose of this research is to develop ultrahigh-speed fiber transmission imaging technique using signal coding by scattering medium. By using multimode fiber as a scattering medium, information transmission via fiber is realized. Object recognition and reconstruction were performed without the imaging process by feeding the observation signal transmitted through the fiber directly to a discriminator such as a neural network and applying a machine learning algorithm.
The principle of this method was confirmed by simulation and demonstration experiment. In this research, it is possible to combine optical measurement and information transmission with low cost and energy saving, and it can be expected to be applied to the imaging of the inside of a closed space such as a remote place or a body.
