Abstract
The feasibility of discriminating and counting asbestos-fiber aerosol particles by means of their shapes, using a two-detector, optical, aerosol counter was determined. The assymmetry of their optical diffraction patterns would distinguish fibers from other, more regular aerosol particles. A laboratory prototype was designed, constructed, tested, modified and retested. The feasibility of counting fibers by means of their optical diffraction patterns, using two detectors, was demonstrated. In the latest version the aerosol fibers were aligned by a combination of fluid-velocity-gradient and electric fields. A description of the latest version, its capabilities and limitations, and a theoretical model of the alignment process are presented.
