The invention provides a method of, and apparatus for detecting and analysing moving particles using an impact responsive transducer, which generates a detection signal having an amplitude related to force of particle impact. The transducer output signal is monitored, and when it exceeds a given threshold, any local maximum values are noted. Those values are compared to determine which has the overall maximum amplitude. A final signal is then generated in order to provide a representation of the maximum value, and hence the momentum and time of occurrence of a particle impact.
L'invention concerne une méthode et un appareil servant à détecter et à analyser des particules en mouvement en utilisant un capteur sensible aux chocs qui génère un signal de détection dont l'amplitude correspond à la force d'impact des particules. Le signal de sortie du capteur est contrôlé et, s'il excède un seuil donné, on relève toutes les valeurs maximum locales. On compare ces valeurs afin de déterminer laquelle possède l'amplitude maximum globale. Un signal final est ensuite généré afin d'obtenir une représentation de la valeur maximum, et, à partir de là, de l'énergie cinétique et du temps d'occurrence d'un choc de particules.
