A PC based laser Doppler velocimeter (LV) data system was developed. The data system uses frequency domain processing for multiple component LV individual signal realization. The system is based on a standard add in board for IBM PC's which has a transient digitizer and programmable digital signal processor (DSP) on board. Custom software written for both the general purpose DSP and the PC is described. The DSP is programmed to implement the frequency domain LV signal processor and the PC is programmed to provide a user interface and data archiving capability. The resulting data system is a low cost alternative to dedicated commercial velocimeter signal processors. Furthermore, the general purpose utility of the PC is still available when LV signal acquisition and processing is not active. Typical optical signal data processing is presented to illustrate data system performance. 5 refs., 7 figs.
