摘要: Over the last ten years or so, new optoelectronic technologies have enhanced design options for laser anemometers, thus extending their versatility. Most obvious is optical fibre beam delivery, now included in many commercial products. Solid state sources and detectors, such as diode lasers avalanche photodiode are used increasingly special applications. Other devices, guided wave modulators holographically formed conditioning optics, beginning to find place.
