Sentences with phrase «laser interferometry»
"Laser interferometry" is a method that uses laser light to measure and analyze changes in distance or movement with high precision. It involves splitting a laser beam into two paths, and when the beams recombine, they create an interference pattern that can be studied to determine any changes or vibrations in the objects being measured. Full definition
«In comparison, laser interferometry systems (which detect movement from changes in interference patterns in a split laser beam which is then recombined) cost about # 20 000 and have a hundred times less resolution.»

She'll just have to brush up on cosmic inflation and perhaps laser interferometry.
Through a method known as laser interferometry, the distance between the reflecting mirrors inside the tunnel can be measured to a very high precision.
The ability to control quantum noise could one day be used to improve the precision of very sensitive measurements, such as those obtained by LIGO, the Laser Interferometry Gravitational - wave Observatory, a Caltech - and - MIT - led project searching for signs of gravitational waves, ripples in the fabric of space - time.
Those ripples are now reverberating through NASA, nudging the agency to mend fences with the European Space Agency (ESA) and rejoin an ambitious mission, called the Laser Interferometry Space Antenna (LISA), to study gravitational waves from space.
Another laser interferometry system will be the evolving Laser Interferometer Space Antenna (eLISA) scheduled to launch in the mid-2030s.
On Jan. 4, the Laser Interferometry Gravitational - wave Observatory (LIGO) picked up a barely perceptible signal that scientists quickly determined to be a gravitational wave — a ripple of energy passing through the curvature of spacetime.
That didn't happen here, although one proposed farm was abandoned because the vibration from the wind turbines would have increased the «seismic noise» at the Laser Interferometry Gravitational Observatory», half of which is located on the Hanford Site, looking for gravitational waves.
