Transcranial Doppler Ultrasonography
Neurosurgery Clinics of North America, 1994Transcranial Doppler ultrasonography is an extremely useful adjunct in neurosurgical intensive care. Continuous improvements in TCD equipment as well as computer software have improved examination success and also vessel identification. Recent expanding applications of TCD have also allowed the study of disorders of control of the cerebral circulation.

The Physics of Fluids, 1975
Narrow linewidth tunable lasers augur a new kind of laser Doppler velocimetry employing resonant absorption and fluorescence from trace atomic species rather than scattering from particles. This technique may provide better turbulence and small volume information than present velocimetry.

Doppler, Inertial, and Doppler-Inertial Techniques
Navigation, 1964The flight characteristics of the supersonic aircraft are such that strong recommendations have been made for self-contained, accurate navigation and flight stabilization equipment. This paper discusses three types of equipment that can supply the required information: Doppler radar navigation systems, inertial navigation systems, and combined Doppler-
