Abstract
L'invention concerne un dispositif portable pour réaliser des analyses sur des substances troubles selon la technique de corrélation croisée tridimensionnelle et pour empêcher l'influence de la diffusion multiple, ainsi que le procédé de réglage de ce dispositif. Le dispositif présenté comporte une plaque de base (1) sur laquelle est monté un laser réglable, dans des dispositifs de basculement ou au moyen d'un miroir servant à diriger le faisceau laser perpendiculairement à la paroi d'une cuvette (6) remplie d'une substance à analyser. Comme diviseur de faisceau (4), on utilise une plaque (7) translucide recouverte partiellement ou complètement d'une couche réfléchissante, qui est fixée rigidement à la plaque de base (1) au moyen d'une fixation de positionnement (8) dont la surface d'appui (16) destinée à la plaque (7) translucide se trouve à un angle fixe par rapport à la plaque de base (1). La fixation de positionnement (8) est reliée rigidement, de façon libérable, à la plaque de base (1) et à une fixation de cuvette comportant des logements pour la cuvette (6) et pour un contenant (70) cylindrique, translucide, rempli du liquide, qui est placé sur la plaque de base (1). Des dispositifs de décalage destinés à la fixation de cuvette (5) et servant au positionnement en continu de celle-ci sont également montés sur la plaque de base. Sur le côté détection du dispositif sont placés des dispositifs de basculement et de décalage, pouvant être positionnés de façon fixe sur une plaque de base, lesquels sont destinés à au moins deux miroirs et à au moins deux optiques de détection, cette dernière plaque de base pouvant être bloquée rigidement sur la plaque de base (1). Le dispositif comprend également un multiplicateur de photons et des corrélateurs assurant les fonctions de corrélation croisée et d'auto-corrélation.
