Abstract

A device and a method for detecting scattered light signals is specified. A light source exposes a scattered light area in which particles may be present to light. With the objective of reducing costs and improving detection accuracy, the device comprises a plurality of optical sensors for detecting scattered light and an evaluation unit for evaluating the signals detected by the optical sensors, wherein the sensors are each arranged at a sensor angle relative to the incident axis of the incident light so as to detect scattered light from the scattered light area, wherein one of the plurality of optical sensors is a reference sensor, and wherein the evaluation unit is designed to relate the signal profiles of the other optical sensors to the signal profile of the reference sensor, wherein the signal profiles of the optical sensors serve in classifying any particles which may be present in the scattered light area.
