The kinesiographic measurement of jaw displacement
The Journal of Prosthetic Dentistry, 1980F unctional movements of the jaw have been recorded by a variety of methods including direct observation, cinematography, electromagnetically inductive and photoconductive transducers, and, most recently, radionuclide tracking.‘. :’ During normal movements, the translations and rotations which accompany jaw motion are so complex that only those systems

Interferometer for measuring displacement and distance
Optics Letters, 1987A simple interferometer for measuring both relative displacement and absolute distance is fabricated that uses a laser diode. The sign of the displacement is detected by means of a lambda/8 plate, and the distance is measured by a FM radar technique of modulating the laser-diode frequency.

Measuring characteristics of the displacement cardiograph
Medical & Biological Engineering, 1973The displacement cardiograph (d.c.g.) is a noncontacting electromagnetic transducer that can be used to measure movement of tissue. In normal operation a sensing probe is placed near the moving tissue, and this produces an output voltage. The d.c.g. detects movement by means of the electromagnetic field it generates.

Assessment of Displacement Measurements by a mmWave Radar
2023 IEEE Sensors Applications Symposium (SAS), 2023Radar vibrometry is a promising technique to measure the vibration of a target through an electromagnetic signal. The capability of a Radar to detect and measure a target vibration is well-known in literature, but an analysis of the attainable performances from a metrological point of view is necessary to understand how such a technology can be used in

Measurement of nasal displacement by photography
The Journal of Laryngology & Otology, 1992AbstractA simple photographic method of assessing a commonly encountered nasal deformity has been devised. The method described is of use in quantifying a subjective appearance and in assessing the result of surgery.

Nanoscale displacement measurement
International Journal of Nanotechnology, 2019Research in the field of nanotechnology requires high accuracy and reliability of the obtained results, i.e., an appropriate metrological support of instruments and equipment is needed, which is used in the measurement of linear dimensions, movements, speeds and accelerations of nano-objects.

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.

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
