1. A system for analysing drops capable of being ejected by a coating product applicator, said system comprising:
a light source configured to illuminate a drop ejection zone, which forms an observation zone;
a first image acquisition device configured to acquire an image of the observation zone;
a second image acquisition device configured to acquire an image of the observation zone;
an image analyser configured to determine, from the image of the observation zone, a presence of drops at a given distance from the coating product applicator, a size of the drops and an absence of satellite;
and wherein the light source and the first image acquisition device are situated on a same side of the observation zone, the second image acquisition device being arranged on the same side of the observation zone as the light source and the first image acquisition device, the first and second image acquisition devices being situated on either side of the light source.
