Interferometers, devices that can modulate aspects of light, play the important role of modulating and switching light signals in fiber-optic communications networks and are frequently used for gas ...

Laser Doppler vibrometers (LDVs) measure vibrations in ways that other sensors can't. From large aircraft structures to microscopic MEMS sensors, and Laser Doppler vibrometers (LDVs) measure ...

An international team of astronomers have used the European Southern Observatory’s Very Large Telescope Interferometer, at the Paranal Observatory in Chile, to image the Eta Carinae star system in the ...

A laser Doppler vibrometer’s (LDV) real-time capability enables measurement times roughly six orders of magnitude smaller compared to any method that is based on strobe techniques or provides a ...

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 ...

Laser vibrometry or more specific laser Doppler vibrometry is a precision optical measurement technology used for determining vibrational velocity and displacement at a fixed point. The laser Doppler ...
