End-View Image Processing Based Angle Alignment Techniques for Specialty Optical Fibers
We propose two end-view-based digital image processing algorithms for high-precision rotational angle alignment of specialty optical fibers. The first technique is based on the cross-correlation calculation between images of two fiber ends.

Grating‐Lens Empowered Metafiber for Large‐Angle Light Collection With 3D Nanoprinted Structures
A grating‐lens‐based Metafiber enables efficient light coupling into single‐mode fibers at large incidence angles. By combining diffraction and focusing on the fiber facet using a 3D nanoprinted holographic structure, light is selectively coupled only at specific angles while suppressing unwanted signals. This approach achieves high coupling efficiency

Effect of Endodontic Sealers on the Bond Strength of Glass Fibre Posts: A Systematic Review
ABSTRACT This systematic review evaluated the influence of resin‐based, eugenol‐based and bioceramic endodontic sealers on the bond strength of glass fibre posts cemented with resin cements. Searches were conducted in PubMed, Scopus, Web of Science, Cochrane Library, Google Scholar and Embase, including in vitro studies using human or bovine teeth ...
