ATLANTA -- A laser-based sensor can measure crosswind speeds for applications such as aviation safety and meteorology, Georgia Institute of Technology researchers report.The single-ended, long-path non-Doppler laser wind sensor registers faint wind movements that an anemometer cannot, while matching the anemometer's accuracy at higher wind speeds, said researcher Mikhail Belen'kii.Originally developed for chemical plants, it is designed for working alongside other sensors that measure airborne chemical concentrations, said principal research scientist Gary Gimmestad. "If you measure the...Read full article
