Abstract
Apparatus and method are provided for measuring a dimension of an airborne fiber. The apparatus includes a flow channel for providing a laminar flow to at least a portion of the fibers in air sample and a light source for projecting a light beam along a selected beam path to impinge upon a first fiber in the sample to create scattered light. A portion of the scattered light is measured by a light detector to produce an electrical output which is related to the fiber's dimension.
