Abstract

A single-ended, non-Doppler, laser wind sensor has been developed to measure path-integrated cross winds by viewing a distant target through a large telescope and observing the motion of a laser speckle pattern. The speed of the moving speckle pattern is determined by a cross-correlation between the signals from two detectors in the telescope focal plane. A prototype laser wind sensor was developed and tested. Results are shown for a laboratory test in a wind tunnel and for an outdoor test in a non-homogeneous wind field. Practical applications of the sensor are discussed, and possible modifications to measure two- or three-dimensional wind fields are described.
