摘要

Improvements to enhance the performance of optical barrier anemometers as to the approach to the walls are proposed. The study of a detector includes a photomultiplier operating in nominal state, avalanche photodiodes, and a photomultiplier operating in supersaturated state. Statistical processing includes the measurement results obtained on a pilot installation. It is shown that it is possible to approach obstacles to within 0.2 mm.
