Optically Heated Long-Period Grating as Temperature-Insensitive Fiber-Optic Refractive-Index Sensor

IEEE Photonics Journal, 2012
A temperature-insensitive fiber-optic refractive-index sensor based on optically heated long-period grating (LPG) is presented. The LPG is manufactured in a short section of cobalt-doped optical fiber (COF), which can be thermally stabilized through a ...

Novel long-period fiber gratings: Fabrication and sensing applications

, 2017
We presented two novel schemes for fabricating micro-tapered long-period fiber gratings (LPFGs) and helical LPFGs, respectively, by periodically tapering and by directly twisting single mode fibers.

Arthroscopic Free Bone Block Transfer Technique Using Iliac Crest Autograft With Anchor‐Button Fixation for Glenohumeral Instability and Glenoid Bone Loss

Arthroscopy Techniques, EarlyView.
Abstract Bone block transfer for the treatment of glenohumeral instability with severe glenoid bone loss or multiple recurrences has grown in popularity in recent years. In this technical note, we described an arthroscopic‐assisted free bone block transfer technique, using a specially designed anchor‐button unit to treat glenohumeral instability caused
