“This dynamic interferometer with a holographic optical element produces four phase-shifted interferograms imaged on a single detector.”

“The flip causes a tiny shift in the cantilever's vibration frequency, which is recorded by the laser interferometer.”

“Some of the light that is reflected from the cylinder groove is scattered, and does not re-enter the interferometer.”

“Researchers use ground-based lasers and optical interferometry to detect gravity waves.”

“The unique advantage of interferometry is that the wavelength or frequency of the radiation used acts as an inherently precise measuring device.”

“Since the field of gravity wave interferometry is still so new, the researchers involved come from diverse backgrounds.”

“Optical interferometers have features that make them versatile platforms for biomolecular sensing.”

“They might even beat the earth-based interferometers in detecting the first authentic gravity wave.”

“They are also used in optical parametric oscillators and some interferometers.”
