Abstract
The invention provides an optical particle sensor which uses light sources of different first and second wavelengths. A first light source is used to detect light scattering and also to determine when a particle reaches a target positional area. In response to the particle being determined to reach the target positional area, a second light source is operated to provide a pulse of light, and light emitted from the particle in response to the pulse of light is detected by the same detector.
