The validity of neglecting the quadratic phase factors is also discussed. For the case of inhomogeneous optical devices with Gaussian profiles, explicit expressions for the transfer functions are calculated through specific Gaussian integrals.journal articlehttp://dx.doi.org/10.1117/12.55961http://opticalengineering.spiedigitallibrary.org/metadata only access535Transfer FunctionLinearityFresnel RegimeÓptica (Física)2209.19 Óptica Física
