MOST existing methods of calibrating vibration pick-ups employ some form of extrapolation, that is, the pick-up is calibrated at low frequencies, where the amplitude can be made large, and the result ...

Optical interference is not only a fundamental phenomenon that has enabled new theories of light to be derived, but it has also been used in interferometry for the measurement of small displacements, ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This interferometer was part of a ...

The resolution of an interferometer is dependent on the linewidth of the illuminating laser, wavelength stability and its absolute wavelength. UniKLasers introduce a range of single frequency lasers ...

For well over 70 years explorers have used seismic survey techniques and seismic wave amplitude interpretation to discover oil and gas. In that time they have relied solely on the measurement of ...
