| titleOfInvention | Wind-speed measurement apparatus for medium altitude |
| abstract | The invention relates to a device for measuring the wind speed at medium altitude by the Doppler effect in the field of light frequencies.n n n It comprises a laser (1) which emits pulses, a telescope (4) which receives the scattered light and an interferometer (10) used to measure the spectral displacement of the scattered light relative to the emitted light.n n n The interferometer is a Fabry-Pérot interferometer in which part of one of the mirrors (30,31) of the interferometer (10) is covered with an extra thickness of silica (34). The spacing of the two mirrors (30,31) and the extra thickness of silica (34) are determined so that the passbands (43,44) of each of the two filters thus produced are centered on the sides of the spectral distribution of backscattered light 42. |
