A novel laser-optical fiber Bragg grating anemometer (FBGA) has been devised for measuring the speed of a moving gas in the range 0-1.5 m s(-1). As a test, the FBGA was applied to measuring the speed of the electric wind generated in the particularly harsh, high-voltage environment of a dc, negative-polarity, partial (corona) discharge in atmospheric air. The instrument proved more stable and yielded an order-of-magnitude improvement in sensitivity (deltav approximately 4 x 10(-3) ms(-1)) compared with other optical-fiber-based anemometers. On-axis wind speeds ranging from zero to 1.1 m s(-1) were measured in the vicinity of the corona discharge.
一种新型的激光 - 光纤布拉格光栅风速计（FBGA）已被设计出来，用于测量0 - 1.5米/秒范围内移动气体的速度。作为一项测试，该FBGA被应用于测量在大气中直流负极性局部（电晕）放电这种特别恶劣的高压环境中产生的电风速度。与其他基于光纤的风速计相比，该仪器被证明更稳定，并且在灵敏度方面有一个数量级的提升（Δv约为4×10⁻³米/秒）。在电晕放电附近测量到了从零到1.1米/秒的轴向风速。
