Abstract

See full text

The invention provides an optical particle sensor (1) comprising:

    at least one light source (2, 2r, 2g, 2b) configured to emit light rays (20),at least one channel (3) intended to receive a fluid transporting at least one particle (30), and to at least partially receive the light rays (20) emitted by the at least one source (2, 2r, 2g, 2b), such that said light rays (20) are partially scattered by the at least one particle (30),at least one photodetector (4) capable of receiving said scattered light rays (20),said sensor (1) being characterised in that the at least one source (2, 2r, 2g, 2b) has an emission face (21) facing one side (D) of the sensor and in that the at least one photodetector (4) has a receiving face (41) facing the same side (D) of the sensor (1), such that the light rays received by the at least one photodetector are light rays (20b) backscattered by the at least one particle (30), for at least 90% of them.
