REGULAR AND QUASI-REGULAR SPECTRA OF DISO RDERING LAYER STRUCTURES

Two examples of problems being solved by statistical optics methods ar e considered. They are clear enough, can be easily interpreted and, do not require difficult calculations. it is shown how the first problem -the influence of random optical length deviations on Fabry-Perot inte rferometer transmission spectra-helps to solve the second one: the 'my stery' of the experimental spectra of multiply domained KH2PO4 crystal s. These examples can be useful for solving other statistical problems .
