Dimensional characterization of large opaque samples and microdeformations by low coherence interferometry
We report on the application of an interferometric system based on the low-coherence interferometry technique to the dimensional characterization of large opaque mechanical parts as well as microdeformations experienced ...
Determination of Nanoscale Mechanical Properties of Polymers via Plasmonic Nanoantennas
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 ...
Inclination shift signal: thickness or index measurement in transparent media by transmission of generally astigmatic Gaussian beams
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. ...
Extending low-coherence interferometry dynamic range using heterodyne detection
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 ...
