Scanning-free imaging through a single fiber by random spatio-spectral encoding

Opt Lett. 2015 Feb 15;40(4):534-7. doi: 10.1364/OL.40.000534.

Abstract

We present an approach for 2D imaging through a single fiber without the need for scanners. A random scattering medium placed next to the distal end of the fiber is used to encode the collected light from every imaged pixel with a different random spectral signature. We demonstrate imaging of externally illuminated 2D objects from a single measured spectrum at the fiber's proximal end. The technique is insensitive to fiber bending, an advantage for endoscopic applications.
