Accurate Measurement of Displacement
Canadian Geotechnical Journal, 1974The effects of lateral displacements on building structures is presently receiving considerable attention.A method is described whereby very accurate measurements of lateral displacement can be made economically.The tensioning device of the Potts Mark II Bore Hole Extensometer is graduated to 0.001 in. (0.0025 cm). Some relatively inexpensive hardware

Measurement of Drug Displacement by Continuous Ultrafiltration
Journal of Pharmaceutical Sciences, 1974Adaptation of the continuous ultrafiltration technique to allow precise measurement of the displacement of one ligand by another from binding sites on human serum albumin is described. The displacement of sodium urate and methyl orange by sodium salicylate is demonstrated with analysis of the number of binding sites and association constants for these ...

Measurements Of Ultrasmall Displacements
Optical Engineering, 1978Techniques for resolving small transverse distances are compared with those for resolving small longitudinal displacements. As the desired resolution becomes finer, there comes a point where both problems are best solved by switching to the transform domain.

Measurement of quasistatic Maxwell’s displacement current
Physical Review A, 1989We have used a superconducting quantum interference device to measure all components of the small magnetic field inside a coaxial capacitor that is being charged at a low frequency (695 Hz). The expected result is that ${B}_{z}$ and ${B}_{\ensuremath{\rho}}$ should be 0 and that ${B}_{\ensuremath{\varphi}}$ should increase linearly from the end of the ...

A Device for Measuring Relative Angular Displacement
Journal of Biomechanical Engineering, 1998A simple, inexpensive, and accurate way to measure relative segmental rotations resulting from torsional loadings locally is described. To measure these rotations, we fabricated a planar spatial linkage (open-loop kinematic chain) requiring only one rotational displacement transducer.

In Vivo Measurements of Human Brain Displacement
SAE Technical Paper Series, 2004Finite element models are increasingly important in understanding head injury mechanisms and designing new injury prevention equipment. Although boundary conditions strongly influence model responses, only limited quantitative data are available. While experimental studies revealed some motion between brain and skull, little data exists regarding the ...

Precise displacement measurement for a local surface
Optics Letters, 2009An optical measurement method to get the in-plane and out-of-plane displacements of a local surface using a laser is proposed. The proposed method simultaneously derives the in-plane and out-of-plane displacements by measuring the shift of interference fringes formed by scattered beams.

Displacement measuring grating interferometer: a review
Frontiers of Information Technology & Electronic Engineering, 2019A grating interferometer, called the “optical encoder,” is a commonly used tool for precise displacement measurements. In contrast to a laser interferometer, a grating interferometer is insensitive to the air refractive index and can be easily applied to multi-degree-of-freedom measurements, which has made it an extensively researched and widely used ...

Diffractographic Dimensional Measurement Part 1: Displacement Measurement
Applied Optics, 1972This is the first of a two-part paper on measurement of displacement and profile using changes in the farfield diffraction patterns of a slit aperture formed between a test and reference object. When applied to displacement measurement the method is very accurate over a considerable range, noncontacting, linear, and easy to use.

Real-time out-of-plane displacement measurement using displacement compensation
Review of Scientific Instruments, 2019To determine out-of-plane displacement, it is challenging to simultaneously implement high resolution, wide range, and real-time measurement. This study proposes a method for displacement compensation based on the Michelson single-point displacement measurement system.
