Scalar Diffraction Efficiency Calculations 8mX!mYO3c
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted h#1:ypA6l
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The /xn|d#4
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths P~7(x7/7~
of the rays are determined by the grating order and local grating spacing. For more details about how the Bg|d2,im
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency fTxd8an{
Calculations” on page 4-116.
