Abstract
SINCE THE EARLY 70'S HIGH SPEED DIGITAL CIRCUIT TECHNIQUES HAVE BEEN APPLIED TO LASER VELOCIMETERY FOR FLOW MEASUREMENT. THE MEASUREMENT TECHNIQUES HAVE BEEN CARRIED OUT IN THE TIME DOMAIN. RECENTLY EVOLVED TECHNIQUES APPLIEDTO RADAR SIGNAL ANALYSIS MIGHT BE SIMILARLY APPLIED TO SUCH MEASUREMENTS. THE INTRODUCTION OF SUB-NANOSECOND DIGITAL LOGIC AND DEVELOPMENT OF LOW COST DIGITAL FILTER IMPLEMENTATIONS PERMIT COMPUTATION OF FREQUENCY DATA DIRECTLY FROM SAMPLE MEASUREMENTS OF THE SIGNAL WAVEFORM. THE INTENT OF THIS EFFORT IS TO REDUCE TO HARDWARE THE RESULTS OF A THEORETICAL INVESTIGATION AND SOPHISTOCATED COMPUTER SIMULATION OF A FREQUENCY DOMAIN LASER VELOCIMETER SIGNAL PROCESSOR. A COMPLETELY OPERATIONAL FDLVWILL BE MANUFACTURED; IMPLEMENTED USING COMMERCIALLY AVAILABLE SILICON TECHNOLOGY. THE SYSTEM WILL SAMPLE AT 10 TO 20 MHZ AND BE USED AS "PROOF-OF-CONCEPT" IN LOW FREQUENCY REGIMES.
