How we sharpened the James Webb telescope’s vision from a million kilometres away

It was put on Webb to diagnose and measure any blur in its images. Even nanometres of distortion in Webb’s 18 hexagonal ...

Demonstration of Large Curvature Radius Shape Sensing Using Optical Frequency Domain Reflectometry in Multi-Core Fibers

Abstract: In distributed shape sensing, the shape reconstruction error is more and more sensitive to the strain measuring error along with curvature radius of ...
