Device and method for detecting dispersed light signals

摘要

The detection device (100) has a light source (10) that is provided in a scattered light region (15). An evaluation unit is set for evaluating the optical sensors (21-30) with respect to an incident axis (11) of incident light in a sensor angle (W1-W10) to detect the scattered light from the scattered light region. The evaluation unit is provided to obtain the waveforms of remaining optical sensors to waveform of reference sensor. The signal characteristics of optical sensors are provided for classifying contained particles in scattered light region. Independent claims are included for the following: (1) a method for detecting scattered light signals; and (2) an inertization system for selectively and automatically controlled-reduction of oxygen content in enclosed space.
