Background:

Light propagation in optical fibers involves random scattering, creating speckle patterns from light escaping the cladding.
Existing fiber optic systems primarily utilize light transmission through the core.

Purpose of the Study:

To demonstrate the retrieval of visual information from the side-scattered light of an optical fiber.
To explore the potential of using side-scattered light for novel imaging and communication applications.

Main Methods:

Imaged visual information into the input facet of a multimode optical fiber with a transparent buffer.
Utilized a convolutional neural network (CNN) to analyze the speckle patterns in the side-scattered light.
Retrieved visual data from multiple locations along the fiber's length.

Main Results:

Successfully reconstructed visual information from the side-scattered light.
Demonstrated that visual data can be extracted from light escaping the fiber cladding.

Conclusions:

Side-scattered light from optical fibers contains retrievable visual information.
This technique opens avenues for developing distributed optical imaging systems.
Potential for novel optical communication links interfaced via the fiber's sides.
