A heterodyne interferometry system with a fiber-optic sensor was developed to measure the temperature history of unburned gas in an engine cylinder. A polarization-preserving fiber and metal mirror ...
A UK and a US company team up to develop seismic sensors based on fiber-optic interferometry. The oil and gas industry is set to benefit from a project that will develop fiber-optic sensors to image ...
for fiber endface and micro-component testing, making interferometry easy and affordable. FiBO® true phase-shifting, Michelson interferometers offer 3D surface mapping and visual defect evaluation ...
A new publication from Opto-Electronic Advances, 10.29026/oea.2023.220085 discuss broadband low-loss all-optical phase modulator using gas-filled hollow-core fiber. Optical phase modulators are key ...
Converting undersea optical cables into environmental sensor arrays, without changing infrastructure
Using an approach that converts one long optical cable into many individual segments capable of detecting activity around them, undersea communications cables could create a vast network of seafloor ...
The quantification of large optics demands metrology systems that operate in the context of turbulence, vibration and additional challenges. Figure 1. Measurement of large optics, such as this 8-meter ...
