(Phys.org)—A team of researchers at Sandia Labs in the U.S. has developed a type of atom interferometer that does not require super-cooled temperatures. In their paper published the journal Physical ...

Atom-interferometric quantum sensors could revolutionize navigation, civil engineering, and Earth observation. However, operation in real-world environments is challenging due to external interference ...

The interferometry training kit enables theoretical and experimental investigation of Mach-Zehnder and Michelson interference phenomena without complex tuning requirements. Possible measurements ...

Mobile gravimetry is an important technique in metrology, navigation, geodesy and geophysics. Although atomic gravimeters are presently used for accuracy, they are constrained by instrumental ...

In the present study, the theoretical framework underlying interferometric measurement using multimode lasers—forming the basis of laser vibrometry—is comprehensively described. A numerical simulation ...

National Atmospheric Research Laboratory (NARL) at Gadanki, an autonomous research institute of Department of Space, is engaged in fundamental and applied research in the field of Atmospheric Sciences ...

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 Doppler vibrometers (LDVs) measure vibrations in ways that other sensors can't. From large aircraft structures to microscopic MEMS sensors, and vacuum enclosures to red-hot mills, LDVs measure ...

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 ...

Author/Title Polytec Inc. Tustin, Calif. Laser Doppler vibrometers (LDVs) measure vibrations where other sensors can't. They accurately track up to 30 MHz with linear phase response, as well as ...
