An apparatus and method for presenting various surfaces of particles within a sample to a sensor device is provided. More particularly, embodiments of the present invention provide a pair of concentric counter-rotating surfaces and a dividing member fixed radially therebetween so as to form a scanning chamber wherein sample particles are reoriented relative to the scanning field of an adjacent sensor device by the counter-rotation of the surfaces and the consequent recirculation of the sample particles through the scanning chamber.
L'invention concerne un appareil et un procédé de présentation de diverses surfaces de particules dans un échantillon à un dispositif de capteur. Plus particulièrement, des modes de réalisation de la présente invention proposent une paire de surfaces concentriques tournant par rotation inverse et un élément de séparation fixé radialement entre elles de façon à former une chambre de balayage dans laquelle des particules d'échantillon sont orientées par rapport au champ de balayage d'un dispositif de capteur adjacent par la rotation inverse des surfaces et la remise en circulation conséquente des particules d'échantillon à travers la chambre de balayage.
