## TL;DR

This paper presents a novel method for real-time, high-resolution, full-color imaging of natural scenes through multimode fibres by statistically reconstructing the inverse transformation matrix, enabling versatile applications.

## Contribution

We introduce a statistical reconstruction approach for the inverse transformation matrix, allowing general-purpose, real-time imaging through multimode fibres without prior training on specific image classes.

## Key findings

- High frame rate, high resolution, full-color imaging achieved
- Demonstrated imaging of natural scenes through long fibres
- Potential applications in secure communication and endoscopy

## Abstract

The optical transport of images through a multimode fibre remains an outstanding challenge with applications ranging from optical communications to neuro-imaging. State of the art approaches either involve measurement and control of the full complex field transmitted through the fibre or, more recently, training of artificial neural networks that however, are typically limited to image classes belong to the same class as the training data set. Here we implement a method that statistically reconstructs the inverse transformation matrix for the fibre. We demonstrate imaging at high frame rates, high resolutions and in full colour of natural scenes, thus demonstrating general-purpose imaging capability. Real-time imaging over long fibre lengths opens alternative routes to exploitation for example for secure communication systems, novel remote imaging devices, quantum state control processing and endoscopy.
