Scalar Diffraction Efficiency Calculations E\N?D
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted fFD:E} >5
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The D[. ; H)V
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths e(/~;"r{
of the rays are determined by the grating order and local grating spacing. For more details about how the G #.(% ,
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency Uf^zA/33
Calculations” on page 4-116.
