Use of motion peculiarities of test particles for estimating degree of coherence of optical fields

Zenkova C. Yu., Gorsky M. P., Soltys I. V. and Angelsky P. O.
We discuss interconnections between the depth of spatial inhomogeneity 
of energy distribution of the optical fields and the velocity of motion of test particles
for the cases of different light scattering mechanisms during interaction with light.
We suggest an additional tool for determining the degree of coherence of
superposing waves that propagate along mutually orthogonal directions and have
orthogonal polarisations, being linearly polarised in the incidence plane. The use of
velocity of the test particles while estimating the degree of coherence of optical
fields is suggested for the first time.
