Scalar Diffraction Efficiency Calculations c7sW:Yzil
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted #Z8<H
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The A5/Q:8b
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths 6 Rg{^E Rf
of the rays are determined by the grating order and local grating spacing. For more details about how the e6,/i
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency Xul<,U~w6
Calculations” on page 4-116.
