Nonimaging speckle interferometry for high-speed nanometer-scale position detection.
We experimentally demonstrate a nonimaging approach to displacement measurement for complex scattering materials. By spatially controlling the wavefront of the light that incidents on the material, we concentrate the scattered light in a focus on a designated position. This wavefront acts as a unique optical fingerprint that enables precise position detection of the illuminated material by simp...
متن کاملImaging high-speed friction at the nanometer scale
Friction is a complicated phenomenon involving nonlinear dynamics at different length and time scales. Understanding its microscopic origin requires methods for measuring force on nanometer-scale asperities sliding at velocities reaching centimetres per second. Despite enormous advances in experimental technique, this combination of small length scale and high velocity remain elusive. We presen...
متن کاملHigh-speed label-free detection by spinning-disk micro-interferometry.
Spinning-disk interferometers are a new class of analytic sensors to detect immobilized biomolecules with high speed and high sensitivity. The disks are composed of a large number of surface-normal self-referencing interferometers, analogous to an optical CD, but operating on the principle of microdiffraction quadrature that achieves sensitive linear detection of bound molecules. The surface-no...
متن کاملHigh-Speed Label-Free Multi-Analyte Detection through Micro- interferometry
Interferometers can detect optical path changes down to a billionth-lambda at the half intensity point at quadrature, (defined when the signal and reference waves are out of phase by ninety degrees). We have fabricated interferometric microstructures on silicon all operating at quadrature. The ultimate capability of this approach is the fabrication of over a billion interferometric biosensors o...
متن کاملEffects of random vibration in high-speed phase-shifting speckle pattern interferometry.
The influence of random vibrations on the performance of a dynamic phase-shifting speckle pattern interferometer is investigated by means of experiments and numerical simulations. Two aspects are evaluated: first, temporal unwrapping reliability, second, vibration-induced phase noise. The former is found to be a significant constraint, even for peak velocities well below the Nyquist velocity li...
