Definitions

  • a further increase of measurement accuracy may be achieved by measuring image parameters of those microobjects only whose U signal no amplitude differs from the set level by not less than a root-mean-square value of photodetector ' s noises inherent in the aforementioned signal and/or by additional measurements of image parameters of microobjects at least at one more level of a signal coming from them.
  • microobjects are studied in a flux, their images are projected on to us a lightsensetive layer of a photodetector (a ruler or a matrix of lightsensetive elements) in an impulse exposure mode, the obtained images are scanned and parameters of a videosignal coming from them are measured.

Abstract

L'invention concerne une catégorie d'outils destinés à l'étude et à l'analyse de particules et de matériaux par des dispositifs optiques. Elle peut être appliquée à la recherche médicale, à la géophysique, à la chimie, à la métallurgie des poudres, à la lutte contre la pollution de l'environnement, etc. L'invention vise à améliorer la précision des mesures. Les micro-objets étudiés sont irradiés par un faisceau de rayons présentant, dans la zone d'irradiation, une taille linéaire maximum du volume de cohérence ne dépassant pas 30 % d'une distance moyenne entre des particules dans l'espace. Les images des micro-objets étudiés sont formées par un système optique et lors de la lecture, leurs paramètres géométriques sont lus au niveau d'un signal dépendant de la cohérence de l'éclairage et de l'angle d'ouverture du système optique.
