Scalar Diffraction Efficiency Calculations Ag}>gbz~G
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted ~KrzJp=5F
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The zvD$N-#`p
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths K);:+s-
of the rays are determined by the grating order and local grating spacing. For more details about how the oIf-s[uH
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency _H%ylAt1j
Calculations” on page 4-116.
