FIELD: physics. ^ SUBSTANCE: initial light field is divided into N sections. Sum of amplitude-phase distributions from every section of initial field I is registered. Sequential conversion of initial field if performed by superimposing headers on section of initial light field with sizes öS=öXöY and coordinates of centers of said sections Xn, Yn, where n=1ÇN. Intensities of said sums are registered for every field sections after each jth conversion and header is used for phase conversion of initial field N times by trial sequential variation of current phase of initial light field by magnitude of phase substituend n on each section to define ä«êê 1,2Ç, N, at which Light field phase increment is determined at center of inlet aperture each section by reiteration Note here that current magnitude of phases is defined as where L is period of averaging. ^ EFFECT: improved power characteristics at intensity metre inlet. ^ 7 dwg |
