包括多个激光源的风速测定装置
摘要：
风速测定装置，包括至少两个激光源(18)在共面的不同方向上发射光束，这样各个发射方向都与一个相垂直的发射方向对应，各个激光源(18)都与以下相关联：-用于聚焦发射光束的部件(16)，-用于接收相应发射光束被空气中的粒子(28)反射之后所获得的反射光束的部件(20)，-用于传送在发射光束与反射光束之间发生的干扰信号的部件(20)，-用于处理已获干扰信号的部件(6)，-光学谐振腔，反射光束被回注至所述光学谐振腔内以获取对发射光束的干扰。
摘要（英）：

This device for determining wind speed comprises at least two laser sources (18) transmitting beams in different coplanar directions and such that each transmission direction has a corresponding perpendicular transmission direction, and each laser source (18) has associated: -means (16) for focusing the transmitted beam, -means (20) for receiving a reflected beam obtained after reflection by a particle (28) present in the air of the corresponding transmitted beam, -means (20) for transmitting an interference signal of interferences occurring between the transmitted beam and the reflected beam, -means (6) for processing the obtained interference signals, -an optical cavity into which the reflected beam is reinjected in order to obtain an interference with the transmitted beam.
