Abstract:
In the scanning molecule counting method which detects light of a light-emitting particle in a sample solution using a confocal or multiphoton microscope, there is provided an optical analysis technique enabling the scanning in a sample solution with moving a light detection region in a broader area or along a longer route while making the possibility of detecting the same light-emitting particle as different particles as low as possible and remaining the size or shape of the light detection region unchanged as far as possible. In the inventive optical analysis technique, there are performed detecting light from the light detection region and generating time series light intensity data during moving the position of the light detection region along the second route whose position is moved along the first route in a sample solution, and thereby, the signal indicating light from each light-emitting particle existing in a predetermined route is individually detected using the time series light intensity data.
Abstract:
Dispositif (10) embarqué sur un véhicule (12) pour mesurer le coefficient de luminance rétroréfléchie (R L ) de marquages routiers (16, 28, 32) à des emplacements successifs. Ce dispositif comprend un dispositif (34,134) d'émission et projection de faisceau lumineux en lumière non cohérente, vers une surface de mesure, des moyens (42) d'acquisition du rayonnement lumineux réfléchi par la surface de mesure, des moyens (44) de traitement du signal, déterminant le coefficient de luminance rétroréfléchie (R L ). Lors d'une mesure du coefficient (R L ) à un emplacement, le dispositif (34,134) d'émission et projection de faisceau lumineux projette une pluralité de faisceaux lumineux (C1 à C32 ; C101 à C132) éclairant chacun une surface éclairée élémentaire (E1 à E32; E101 à E132). Une surface éclairée cumulée (41) étant la réunion des surfaces éclairées élémentaires, à chaque instant pendant la mesure audit emplacement, la surface éclairée est strictement incluse dans la surface éclairée cumulée (41), grâce à quoi le système consomme une puissance instantanée réduite, et peut présenter une largeur de mesure importante. Procédé de mesure associé.
Abstract:
The present invention relates to a backscattering apparatus and method for optical scanning along a circular path using one or more optical illuminators and receivers. More particularly, it relates to an apparatus and method of focusing one or more beams of light into one or more beam spots, scanning the common beam spot(s) across a circular path and receiving light backscattered from the beam spot(s) with one or more detectors. A rotationally mounted scanning optics having an optical axis parallel to but not coaxial with the axis of rotation is used to accomplish these functions. A motor may be operatively linked to the scanning optics to cause the same to rotate at a constant angular velocity whereby, with appropriate signal generating detector and signal processing electronics, the number and size of particles suspended in a fluid medium exposed to the beam spot(s) can be determined.
