1. A system for determining wind speed and direction that measures transverse and parallel components of a wind vector relative to coherent energy propagation, comprising:
a plurality of emitters arranged to emit coherent energy in a direction substantially transverse to a direction of wind to be measured;
at least one linear detection array operatively positioned relative to the plurality of emitters such that images from the plurality of emitters are in focus along the at least one linear detection array in accordance with the Scheimpflug condition;
a computing circuit configured to process data signals from the at least one linear detection array, the computing circuit being further configured to analyze the data signals from the at least one linear detection array so as to identify a time difference to overlap between data signals resulting from each of the plurality of emitters.
