Abstract

L'invention concerne un dispositif pour mesurer la distribution directionnelle d'énergie rayonnante reradiée par une particule, pour une caractérisation de cette dernière. Selon l'invention, il comporte une source 22 d'énergie rayonnante projetant un faisceau incident le long d'un premier axe, une zone de détection 126 sur cet axe, un moyen 134, 136, 138, 140, 142, 144 pour déplacer les particules dans la zone de détection pour produire une reradiation avec dispersion de l'énergie rayonnante du faisceau, un moyen 148 pour recueillir une partie de l'énergie rayonnante reradiée, un moyen 119 de collimation, un moyen 120' de déviation de l'énergie rayonnante collimatée, un moyen 121 de focalisation, et un moyen 150-157 pour mesurer l'intensité de l'énergie rayonnante focalisée. L'invention s'applique notamment à l'étude des particules.The invention relates to a device for measuring the directional distribution of radiant energy reradied by a particle, for a characterization of the latter. According to the invention, it comprises a source 22 of radiant energy projecting an incident beam along a first axis, a detection zone 126 on this axis, means 134, 136, 138, 140, 142, 144 for moving particles in the detection zone to produce reradiation with scattering of the radiant energy of the beam, a means 148 for collecting part of the reradied radiant energy, a means 119 for collimating, a means 120 'of deflection of the beam collimated radiant energy, a focusing means 121, and a means 150-157 for measuring the intensity of the focused radiant energy. The invention applies in particular to the study of particles.
