Abstract

A single component, visible wavelength, heterodyne laser Doppler anemometer was constructed based on solidstate laser diode technology for use in fluid dynamic research. With the recent advancements in solid-state laser diodes and solid-state avalanche photodiodes, it is possible to construct miniature laser Doppler anemometer systems solely employing solid-state technology. Such systems have the advantages of small size, light weight, lowpower consumption, low cost, and ruggedness. The subject of the current research was to quantitatively evaluate a miniaturized laser Doppler anemometer system constructed with visible laser diodes and an avalanche photodiode detector. Evaluation measurements in a turbulent, stagnating jet are presented and compared to both hot-wire and five-hole probe data. The miniature solid-state laser Doppler anemometer system was found to agree within 2% for mean velocities and agree within 5-20% for root mean square turbulent velocities.
