Scalar Diffraction Efficiency Calculations +S0u=u65
CODE V estimates the scalar diffraction efficiency, or the amount of energy going into a given diffracted hho%~^bn(
order, for a number of blazed grating structures: kinoform, stepapproximation to a kinoform, or sinusoid. The ,i![QXZ
grating structure determines only the diffraction efficiency of the rays; the direction and optical path lengths ]wf |PU~nr
of the rays are determined by the grating order and local grating spacing. For more details about how the 5mIXyg 0:
diffraction efficiency is calculated for each of the blazed grating structures, see “Scalar Diffraction Efficiency Oxj(g;}
Calculations” on page 4-116.
