Paper Abstract

Existing multiple applications require informative description of spatial or temporary structure of the fields scattered on the objects under study. In virtue of the random nature of scatter, descriptions of partially or quasi-coherent fields must be in statistical terms and reflect at the same time spatial or temporal structural regularities of the observed physical variables related to scattered fields. The paper considers descriptions preserving important phase relations between spatial or temporal components of scattered fields. A description is proposed dwelling upon the observed estimate of the field density operator and having the form of joint distribution of physical variables related to the space-time field envelope and its Hilbert- image. The description is oriented to recognition and estimation of the parameters of both stationary and non-stationary optical fields.
