Approximation of the Fraunhofer diffraction peak, produced by particles of arbitrary shape

Not Accessible

Your library or personal account may give you access

Abstract

A simple analytical formula is developed to describe light diffraction by chaotically oriented particles of arbitrary shape. The formula expresses the angular pattern through three well-defined microphysical characteristics of an ensemble: the average cross-sectional area, the average area squared, and the average length of the contour bordering the particle projection.
