Wind parameter determination at various distances using a sensor based on Particle Tracking Velocimetry

A novel optical wind sensor, which is able to measure the wind in a distance with the help of optical techniques, is presented here. The problem of conventional wind measuring systems is that they measure the wind locally where the wind sensor is located. In some monitoring systems, for example in weather based dynamic line rating for overhead lines, it is necessary to measure the wind in a certain distance. The paper introduces a new optical wind sensor based on Particle Tracking Velocimetry and shows results how such a sensor can perform and how it is possible to increase the measuring range of the wind sensor.
