Paper Abstract

The analysis of scattering characteristics of diffractive optics based on Finite-difference time-domain method is presented. And its scattering pattern along the surface is gotten. It shows that the scattering intensity in the discontinuous surface is much higher than the continuous surface. This causes the decrease of diffractive efficiency. Binary optics with multilevel relief can cause more scattering than micro optics with continuous relief, so it is not suitable for being used in the situation where phase varies rapidly.
