Scalar Diffraction Efficiency Calculations Q<(YP.k
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted <skajQQ
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The c64v,Hj9
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths O(Jj|Z
of the rays are determined by the grating order and local grating spacing. For more details about how the EbY,N:LK
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency Ms^dRe)
Calculations” on page 4-116.
