New System

The paper presents the method, configuration and calibration of special system for measuring the size of particles. It is designed for real-time measurement of particles in the range up to 10µm, moving with velocity up to 15m/s and under pressure up to 20 bar. The method is based on measuring light scattered by single particle. We focused on studying the output from photomultiplier and finding relationships between pulse shape and particle size, and also the time intervals between pulses.

Particle Measurement

The accurate determination of dust levels on optical surfaces is necessary to assess sensor system performance. A comparison study was made on several particle measurement methods including those based on direct imaging and light scattering. The effectiveness of removing the particles from the surface prior to determining particle size distributions was also assessed. These studies revealed that some methods, especially those requiring particle removal before analysis, are subject to large systematic errors affecting particle size distributions. Thus, an understanding of the particle measurement methods employed is necessary before any surface cleanliness or obstruction value assignments are accepted as a true representation of an optical surface contamination condition.
