Short summary
Volcanic eruption can be a serious security risk for airplanes. We develop a new aerosol sensor for the reliable detection of volcanic ash on airplanes. We introduce here the laboratory prototype of this instrument, which is able to distinguish between water droplets and volcanic ash particles by measuring the scattered light at two distinct wavelengths simultaneously. The different optical behaviour of volcanic ash and water at these wavelengths makes this differentiation possible.
