都卜勒測風光達 / 邊界層剖風儀

使用 1.5 μm 雷射超外差（Heterodyne）技術，獲取大氣晴空微弱散射訊號，並經由毫秒級快速傅立葉平行運算進行頻譜分析，推算大氣三維風速風向與空氣總懸浮微粒濃度。系統緊緻可快速佈署，遠距精準測量，無傳統風速計機械偏差，取代傳統測風塔。

Utilizing 1.5 μm laser heterodyne technology, the system captures faint backscatter signals from clear-air conditions. Through millisecond-scale parallel Fast Fourier Transform (FFT) spectral analysis, it derives 3D atmospheric wind speed and direction as well as total suspended particulate concentrations. Compact and rapidly deployable, the system offers precise long-range measurement and eliminates the mechanical errors associated with traditional anemometers, serving as a replacement for conventional wind-monitoring towers.
