Scalar Diffraction Efficiency Calculations /1.gv~`+
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted X @X`,/{X
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The J,k.*t:
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths a)!R4
of the rays are determined by the grating order and local grating spacing. For more details about how the jK2gc^"t
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency \# 1p
Calculations” on page 4-116.
