Determination of Nanoscale Mechanical Properties of Polymers via Plasmonic Nanoantennas
(2020-06-02)
Nanotechnology and the consequent emergence of miniaturized devices are driving the need to improve our understanding of the mechanical properties of a myriad of materials. Here we focus on amorphous polymeric materials ...
Extending low-coherence interferometry dynamic range using heterodyne detection
(2020-08)
Low-coherence interferometry (LCI) technique is generating considerable interest in industrial applications where there is a need for larger measurements with high resolution. Conventional Fourier domain systems reach a ...
Inclination shift signal: thickness or index measurement in transparent media by transmission of generally astigmatic Gaussian beams
(2021-04)
The focus error signal is a widespread optical technique that harnesses the shape of a simply astigmatic Gaussian beam to produce an output signal with a well-defined linear range used for many different applications. ...
