Abstract
Dispositivo de determinación de la velocidad del viento que incluye al menos dos fuentes láser (18) que emiten haces coplanares en diferentes direcciones, a cada fuente láser (18) estando asociados: - unos medios de focalización (16) del haz emitido, - unos medios de recepción (20) de un haz reflejado obtenido después de reflexión por una partícula (28) presente en el aire del haz emitido correspondiente, - unos medios de transmisión (20) de una señal de interferencias que intervienen entre el haz emitido y el haz reflejado, - unos medios de tratamiento (6) de las señales de interferencias obtenidas, incluyendo cada fuente láser (18) una cavidad óptica en la que se reinyecta el haz reflejado para obtener una interferencia con el haz emitido, caracterizado por que incluye cuatro fuentes láser (18) que forman dos pares de fuentes, por que cada par de fuentes define un sistema de referencia ortogonal en el plano, por que los dos sistemas de referencia ortogonales definidos de este modo presentan un mismo origen, y por que los dos sistemas de referencia ortogonales están desfasados entre sí en un ángulo superior a 10°.
