Abstract
PURPOSE:To avoid electrical adverse effect such as lightening, by enabling the measurement of wind direction and wind speed with a single instrument using optical fiber at the same time. CONSTITUTION:A main body 1 is rotary-freely borne to the rotating shaft 7 via bearings 9 and it comes to a position opposing to a wind with a tail wing 5. At the upper end of a rotating sleeve 13 fitted to the main body 1, a wind direction detecting ring shape disc 25 is fitted, which forms a pattern slit in coding and the direction or rotation of the disc 25 is detected with a pair of optical fibers 30, 30'. A light shield member 41 turns with the revolution of a propeller 3 to shut the light between optical fibers 40A, 40A' and the wind speed can be measured with the number of shuttings.
