Abstract

An introduction to elements of diffraction theory of coherent scattering of vector waves for size & velocity measurements is proposed to discuss. In traditional approach, a square-law detection is to observe beating (fluctuation) in optical signal consists of two components: scattered and not-scattered scalar waves. The basis of proposed analysis is to consider mixing on a photodetector of two coherent vector waves with variable states of their vectors of polarization. Vectorial optical signal for spectral analysis is considered in framework of Fraunhofer diffraction for scattering of two plane vector waves by a single particle in case of periodical modulation of an angle of vector polarization described by Jones vector. The formalism of Jones matrix is proposed to describe coherent scattering by a distribution of particles to control their sizes and velocities. A portable spectrometer for Coherent Light Beating Spectroscopy (CLBS) for size & motility application in biology is described.
