We have evaluated a modified delay-and-sum (DAS) beamforming algorithm for breast cancer detection with a microwave radar-based system. The improved DAS algorithm uses an additional weight factor calculated at each focal point to improve image qualit

In this study a method of analysing ground reaction forces was developed to help in the diagnosis of subclinical flexor tendon injury. A Kistler force plate was used to obtain records from a population of Thoroughbreds in National Hunt training over

Contrast thresholds for, and contrast matches between, stationary gratings of three spatial frequencies (0.5, 2, and 8 c/deg) were measured on eight subjects with a history of schizophrenia, just before, and again two to three days after, a therapeut

The characteristic speckle pattern formed when imaging a scattering surface illuminated by laser light retains phase information, which can be used for interferometric measurement of surface displacement. The application of this principle to measurin

The theoretical interpretation of speckle pattern interference fringes produced by small surface displacements is considered. New arrangements for a speckle pattern interferometer are described. Firstly the object is illuminated by plane wavefronts p

An optical facility is described for the study of the vibrational behavior of engineering test pieces. Time-average holography and electronic speckle pattern methods of analysis are combined into one system. The speckle pattern method is used for the
