Spectral analysis of wind turbulence measured by a Doppler Lidar for velocity fine structure and coherence studies
Turbulence in the Kolmogorov inertial subrange has been measured remotely by a line-averaging range-gated pulsed coherent Doppler Lidar, i.e., a commercially available wind Lidar (Leosphere WindCube WLS7) modified in order to stare horizontally into the approaching turbulent flow at a platform situated at 125 meters height in the meteorology tower at Risø DTU, Denmark. Time series of wind turbu...
متن کاملWind Retrieval Algorithms for the Wind Products of the Airborne Coherent Doppler Lidar
The airborne coherent Doppler lidar could provide the wind velocity relative to the motion of the lidar. The retrieval algorithms are complex corresponding to Ground-based lidar, due to the Doppler shift caused by mobile platform. This article gives a thorough analysis of the wind retrieval algorithms for the wind products of airborne Doppler lidar, include the correction for the lidar velocity...

BACKGROUND The capillary blood flow of the nailfold can be measured by means of modern non-invasive techniques like the videocapillary microscope in vivo. To quantify the capillary blood cell velocity, apart from the nailfold capillaries, we used a new technique, the so-called laser Doppler anemometry (LDA). OBJECTIVE The present study investigated how far laser Doppler fluxmetry (LDF), trans...
متن کاملCorrelation of abnormal intracranial vessel velocity, measured by transcranial Doppler ultrasonography, with abnormal conjunctival vessel velocity, measured by computer-assisted intravital microscopy, in sickle cell disease.
The Stroke Prevention Trial has confirmed that utilization of transcranial Doppler ultrasonography (TCD), which examines blood flow in large intracranial vessels, can identify children with sickle cell disease (SCD) who are at high risk of developing a premature stroke. It is not known to what extent the vasculopathy in SCD involves small vessels and whether the abnormalities, if present, corre...
