Scalar Diffraction Efficiency Calculations |m?vVLq
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted qy!Ou3^
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The >(tn "2
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths ~ZlC
'
of the rays are determined by the grating order and local grating spacing. For more details about how the j#6|V]l
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency p'?w2YN/
Calculations” on page 4-116.
