Scalar Diffraction Efficiency Calculations 6CV9ewr
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted 0|}]=XN^
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The \) FFV-k5
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths Wik8V 0(
of the rays are determined by the grating order and local grating spacing. For more details about how the W5^<4Ya!
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency W]CsKN,K
Calculations” on page 4-116.
