Abstract
The present invention relates to a particle detector comprising at least an optical device configured to emit a luminous radiation; and a substrate extending in a plane and defining a channel intended to receive particles, the channel extending principally in a direction perpendicular to the principal plane; characterised in that the detector comprises a matrix of photo detectors and a reflecting surface; the matrix of photo detectors and the reflecting surface being disposed on mutually parallel planes and situated on either side of said portion of the substrate so that a part of the luminous radiation passes through the channel by being diffracted by a particle, then reflects off the reflecting surface, and then reaches the matrix of photo detectors.
