Scalar Diffraction Efficiency Calculations =i>F^7)U1
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted (Tb0PzA
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The Jl4XE%0
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths ,(W98}nB
of the rays are determined by the grating order and local grating spacing. For more details about how the `'.x*MNF
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency \'=}kk`
Calculations” on page 4-116.
