TL;DR: An endoscope combining HSI and white light to correct for image distortion during freehand operation is demonstrated, which allows image distortions to be compensated computationally and an accurate hyperspectral data cube to be reconstructed as the endoscope moves in the lumen.

TL;DR: In this article, the authors investigate the mode coupling in the ring-core fiber (RCF) supporting five or seven guided mode groups (MGs) at a wavelength of 1550nm.

TL;DR: In this paper, a single-step grayscale lithographic process was proposed to enable fabrication of bespoke MSFAs based on the Fabry-Perot resonances of spatially variant metal-insulator-metal (MIM) cavities, where the exposure dose controlled insulator (cavity) thickness.

TL;DR: In this paper, the feasibility of MDM for implementing multiple-input multiple-output (MIMO)radio-over-fiber (RoF)distributed antenna systems (DAS) is experimentally demonstrated, where the MIMO algorithm is able to reconstruct the data signals by overcoming distortion and cross-talk in both the free-space RF and optical fiber channels.

TL;DR: In this article, a thin stack of structured metasurface reflectors is used at the distal facet to introduce wavelength-dependent, spatially heterogeneous reflectance profiles, and the reflected data at 3 wavelengths can be used to unambiguously reconstruct the full TM by an iterative optimisation algorithm.
