摘要
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 de, negative-polarity, partial (corona) discharge in atmospheric air. The instrument proved more stable and yielded an order-of-magnitude improvement in sensitivity (Delta nu approximate to 4 x 10(-3) ms(-1)) compared with other optical-fiber-based anemometers. Onaxis wind speeds ranging from zero to 1.1 m s(-1) were measured in the vicinity of the corona discharge. (c) 2006 Optical Society of America.
