Abstract: In a method of monitoring in-flight particles, a mask in a is places in a plane generally parallel to the direction of travel of the particles. The mask defines at least two slits that are generally parallel and lie in a direction having at least a component at right angles to the direction of travel. The have their ends offset relative to each other. The radiation emitted, scattered or absorbed by the particles is monitored as they traverse the slits. The particles for which the radiation, emitted, scattered or absorbed at each slit as they sequentially traverse said slits bears a predetermined relationship are identified, and the size of the identified particles is determined from the amount of radiation emitted, scattered or absorbed as the identified particles traverse the slits.

The mask defines at least two slits that are generally parallel and lie in a direction having at least a component at right angles to the direction of travel. The slits have their ends offset relative to each other. The slits radiation emitted, scattered or absorbed by the particles is monitored as they traverse the slits field of view. The particles for which the radiation, emitted, scattered or absorbed which is collected through each slit as they sequentially traverse said slits bears a predetermined relationship are identified, and the size of the identified particles is determined from the amount of radiation emitted, scattered or absorbed as the identified particles traverse the slits.
