Not just the Internet: Foresight uses fiber optics to detect structural damage after earthquakes
A new method based on optical interferometry, to monitor structural damage to buildings hit by earthquakes in real time, is the outcome of the Foresight research project, led by the Politecnico di ...
For more than 50 years, phase-shifting interferometry has been the technology of choice for high-precision surface form ...
Large-scale atom interferometers, analogous to optical interferometers but measuring the difference in phase between atomic matter waves on different paths, are intended to be key elements in future ...
Sydor Optics acquired Vertex Optics, expanding precision optics capabilities ahead of a new manufacturing facility in ...
The GRAVITY instrument on ESO's Very Large Telescope Interferometer (VLTI) has made the first direct observation of an exoplanet using optical interferometry. This method revealed a complex ...
March 27 (UPI) --For the first time, the Very Large Telescope's GRAVITY instrument has observed a distant exoplanet using optical interferometry. Observations of the exoplanet's atmosphere revealed ...
Laser self-mixing interferometry (SMI) harnesses the phenomenon of optical feedback by reinjecting a fraction of a laser’s output back into its cavity. This reinjection leads to an interference effect ...
