Scalar Diffraction Efficiency Calculations D'DfJwA
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted bwMm#f
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The ;$wVu|&
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths m&,(Jla
of the rays are determined by the grating order and local grating spacing. For more details about how the Z=o2H Bm7
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency z$. 88^
Calculations” on page 4-116.
