ABSTRACT

A number of definitions of entropy in optics have both advantages and disadvantages. The major features of different entropy definitions are briefly characterized. The principal distinction between the statistics entropy definition and the thermodynamics one is indicated. The diffraction-caused radiation entropy is calculated.
