The signal-conditioning electronics used to interface a recently developed Bragg cell-type vector velocity laser velocimeter LV to a signal processor and data acquisition system are described. The Bragg cell LV elininates the 180-deg velocity direction ambiguity problem of the conventional LV but in turn imposes a unique signal-conditioning problem. The signal characteristics and the signal-conditioning problem are defined, and signal-conditioning electronic circuits are described. Initial LV system evaluation data are presented for two orthogonal velocity component, atmospheric wind measurements. The Bragg cell LV-electronics system is shown to be readily expandable to a three-dimensional vector velocity measurement system. Author
