Abstract

Optical designers currently have several ways to model surface relief diffractive optical elements (DOE's) on the computer. We are aware of three distinct techniques: the phase model^1,2, the Sweatt model³ and the Southwell model⁴. We will compare them for accuracy, applicability and ease of use. These models must perform two functions: a) Accurately simulate the performance of the DOE. b) Be translatable into information that will allow the physical part to be produced.
