Scalar Diffraction Efficiency Calculations Rxq4Diq5k
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted IqFmJs|C
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The ujLje:Yc
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths zgl$ n
of the rays are determined by the grating order and local grating spacing. For more details about how the f{-,"6Y1
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency )Vo%}g?6!
Calculations” on page 4-116.
