Rapid measurement of three-dimensional diffusion tensor [PDF]
The Journal of Chemical Physics, 2007 In this article, the authors demonstrate a rapid NMR method to measure a full three-dimensional diffusion tensor. This method is based on a multiple modulation multiple echo sequence and utilizes static and pulsed magnetic field gradients to measure diffusion along multiple directions simultaneously.

A Three-Dimensional Position Measuring System
IFAC Proceedings Volumes, 1986 Abstract When checking robot performance, a measuring system with the ability to measure both the static and dynamic behaviour of a robot arm is essential. The system can also be used to check on robot performance and on validity of already developed models.

A resolution measure for three-dimensional microscopy [PDF]
Optics Communications, 2009 A three-dimensional (3D) resolution measure for the conventional optical microscope is introduced which overcomes the drawbacks of the classical 3D (axial) resolution limit. Formulated within the context of a parameter estimation problem and based on the Cramer-Rao lower bound, this 3D resolution measure indicates the accuracy with which a given ...

Three-Dimensional Measurement System
, 1993 We have developed a system that uses multiple radiographic views and modern survey instruments to determine the locations and sizes of hidden objects. The survey instrument is a total station that combines a transit for angle measurements and a range finder for determining the exact locations of the film plane and radiographic source for each ...
