Abstract: A method for identifying an obstacle (O) in the laser beam (F) of a lidar system includes: commanding the transmission of a laser beam (F); and receiving a lidar signal (S) corresponding to the reflection of the beam (F) on a diffuser present in the beam (F). The detection method further includes: evaluating a set of first parameters of the lidar signal, the set of first parameters including at least an amplitude and a duration, a first detection moment being defined for the lidar signal (S), the duration being defined at each moment as the time elapsed since the first detection moment; identifying an obstacle (O) present in the beam (F) when the amplitude is greater than a first threshold and the duration is greater than a second threshold; and decreasing the power of the beam (F).

Abstract: The present invention relates to a method for self-testing an angle-of-attack probe comprising the steps of controlling an angular excitation of a rotary element that is rotatable about its equilibrium position according to known excitation characteristics; acquiring angular measurements relating to the rotation of the rotary element, determining a parasitic torque applied to the rotary element on the basis of the angular measurements and of the excitation characteristics; comparing at least one component of the parasitic torque with at least one predetermined threshold and detecting an operating fault in the probe when said component exceeds the predetermined threshold.

Abstract: A method for estimating the transverse component Vtrans of the velocity of the air comprises the following steps: emitting a focused laser beam; acquiring an electrical signal resulting from the transit of a particle across the beam at a point of transit; analysing the signal so as to obtain a spectrogram revealing an elongate mark representative of the transit; estimating the duration of traversal of the laser beam by the particle and the slope of the mark; deducing from the duration and from the slope the distance between the point of traversal of the beam and the focusing point; determining the radius of the beam at the point of transit; deducing the transverse component from the radius and from the duration.
