Scalar Diffraction Efficiency Calculations ),>whC tsI
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted CZ!gu Y=
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The _WGWU7h
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths hwQrmVwvP
of the rays are determined by the grating order and local grating spacing. For more details about how the ^V~^[Yp
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency
