Abstract
An optical particle sensor includes-at least one light source configured to emit light rays; at least one channel intended to receive a fluid transporting at least one particle, and to at least partially receive the light rays emitted by the at least one source such that said light rays are partially scattered by the at least one particle; and at least one photodetector capable of receiving said scattered light rays. The at least one source has an emission face facing one side of the sensor and the at least one photodetector has a receiving face facing the same side of the sensor, wherein the light rays received by the at least one photodetector are light rays backscattered by the at least one particle, for at least 90% of the light rays.
