Beat wave interferometry for measuring relative motion.
نویسنده
چکیده
A new approach to detecting relative motion is proposed based on measuring the beat frequency. A formula is derived for the beat frequency as a function of the speed of translation. A principal sketch of an experimental setup implementing the new idea is proposed, and the effects of possible small differences in the frequencies and phases of the sources are discussed.

Estimating near-surface shear wave velocities in Japan by applying seismic interferometry to KiK-net data
We estimate shear-wave velocities in the shallow subsurface throughout Japan by applying seismic interferometry to the data recorded with KiK-net, a strongmotion network in Japan. Each KiK-net station has two receivers; one receiver on the surface and the other in a borehole. By using seismic interferometry, we extract the shear wave that propagates between these two receivers. Applying this me...
متن کاملProbing the dynamics of an optically trapped particle by phase sensitive back focal plane interferometry.
The dynamics of an optically trapped particle are often determined by measuring intensity shifts of the back-scattered light from the particle using position sensitive detectors. We present a technique which measures the phase of the back-scattered light using balanced detection in an external Mach-Zehnder interferometer scheme where we separate out and beat the scattered light from the particl...

A novel nondestructive testing (NDT) method where measurement of large object deformations using temporal evolution of the speckles in speckle interferometry is reported. Basic principle of the method is continuous object deformation is introduced and the fluctuations in the phase of the speckle as intensity modulation is recorded. Acquiring a large number of frames of the object motion the pha...
متن کاملMeasuring nanoparticle size using optical surface profilers.
Optical surface profilers are state-of-the-art instruments for measuring surface height profiles. They are not conventionally applied to nanoparticle measurements due to the presence of diffraction artifacts. Here we use a theoretical model based on wave-optics to account for diffraction-based artifacts in optical surface profilers. This then enables accurate measurement of nanoparticles size o...

Digital Holographic interferometry is a powerful and widely used optical technique for accurate measurement of variations in physical quantities such as density, refractive index, and etc. In this study, an experimental digital holographic interferometry setup was designed and used to measure the amount of energy changes induced by absorption of radiation from a non-ionizing infrared laser beam...
