Area of Science:

  • Optics and Photonics
  • Biomedical Imaging
  • Machine Learning

Background:

  • Supervised deep learning enhances fiber-optic imaging but requires paired data, limiting flexibility.
  • Existing fiber optic methods struggle with high sampling density needed for unsupervised reconstruction.
  • Disordered fibers offer a novel approach for high-quality imaging through Anderson localization.

Purpose of the Study:

  • To demonstrate unsupervised full-color imaging with cellular resolution through meter-long disordered fibers.
  • To develop a flexible and robust fiber-optic imaging system independent of paired data collection.
  • To advance unsupervised image reconstruction techniques for challenging imaging scenarios.

Main Methods:

  • Utilized meter-long disordered optical fibers for image transmission.
  • Implemented a two-stage unsupervised image reconstruction process.
  • Employed pixel-wise standardization and a generative adversarial network (GAN).

Main Results:

  • Achieved unsupervised full-color imaging with cellular resolution in transmission and reflection modes.
  • Demonstrated high-fidelity cell imaging within a 4 mm working distance.
  • Showcased imaging robustness with a bent fiber (60° central angle) and enhanced cross-domain generality.

Conclusions:

  • Unsupervised reconstruction with disordered fibers offers a flexible alternative to supervised methods.
  • The developed technique provides high-fidelity, robust, and versatile cellular imaging capabilities.
  • This approach broadens the applicability of fiber-optic imaging in various conditions and for unseen objects.
