Digital interferometry: techniques and trends for fluid measurement
Heat and Mass Transfer, 2007Interferometric based measurement techniques have long played a significant role in enabling insight and understanding into the flow and heat transfer processes in a wide range of fluid flow situations. In recent years, with the advent of digital processing techniques, full field quantitative data can be obtained from interferometric data with relative

A technique for real-time digital measurements in laparoscopic surgery
Surgical Endoscopy, 2004The current techniques for the measurement of intracorporeal targets in laparoscopic surgery are relatively cumbersome and imprecise.A structured light technique was used to obtain the length and width of two defects and an object in a laparoscopic training box.

Digital Technique for Rapid Measurement of Time Lags
Review of Scientific Instruments, 1964A commercial 10-Mc digital chronometer has been used to measure time lags to breakdown in SF6/air mixtures. This method is much quicker than taking measurements from oscillograms and gives greater accuracy when a very wide range of time lags occurs for the same experimental condition. Precautionary measures against pickup from high voltage circuits are

Digital technique for the simultaneous measurement of velocity and temperature
Review of Scientific Instruments, 1978A computer-oriented, hot-wire anemometer technique for the simultaneous measurement of velocity and temperature in heated turbulent flows is described. This technique involves conversion of analogue anemometer voltage signals into digital forms and processing of these latter on a digital computer, in accordance with the anemometer response equations ...

Abductor Digit Minimi Opponensplasty: Technique, Modifications, and Measurement of Opposition
Techniques in Hand & Upper Extremity Surgery, 2010The abductor digiti minimi is one of several muscles described as transfers for restoration of thumb opposition, a critically important function. This operation, also known as the Huber opponensplasty, is most commonly used for reconstruction of opposition in children with type 2 or 3a thumb deficiency, when it is often combined with Z-plasty of the ...

Digitally subtracted linear tomograms: Three techniques for measuring condylar displacement
Oral Surgery, Oral Medicine, Oral Pathology, 1991Using digital subtraction enhancement, we compared the accuracy of three tomographic technique variations for quantifying small changes of condylar position. A phantom made of skeletal material and an adjustable mechanical stage provided 0.1 mm positioning accuracy of the condylar segment.

Comparison of scatter measurement techniques in digital fluoroscopy
Physics in Medicine and Biology, 1993A number of slightly different methods of scatter measurement using the Pb disk technique are described in the literature. These methods are based on applying different forms of data extrapolation to determine the disk-free scatter signal, and it is possible to infer that different results might be obtained.
