Outline of Final Research Achievements

Noting the symmetry between space and time variables in the wave equation, a new realm of statistical optics, called spatial statistical optics, has been created in which the ensemble average is replaced by the spatial average, rather than by the time average in conventional statistical optics.
The following results have been achieved. (1) The conditions on a source and an optical system have been clarified for the statistical field to have wide-sense spatial stationarity. (2) The theory and the method of experiment have been proposed for spatial statistical analysis of vectorial optical fields. (3) The methods for generation of polarization speckle fields with a birefringent scatter plate and their spatial statistical analysis have been proposed. (4) New imaging techniques have been proposed that are based on spatial statistical optics.
