Abstract

The proper operation and performance of optomechatronic systems is fundamentally affected by changes of the relative geometry caused by thermal influences; mechanical displacements and vibrations. Such extrinsic and intrinsic disturbances can be compensated by active control of optical elements like lenses; diffraction gratings or laser sources. In the context with system design and performance analysis tasks it is big challenge to model and simulate the coupled optomechatronic behavior including closed-loop control and disturbances properly on a representative level.

A promising approach is the integration of diffractive optic models in the well established physical object oriented modeling environment Modelica®; which offers already a broad support of multidomain libraries; e.g. electrical; mechanical and thermal.

Therefore the basic modeling requirements for diffractive optical elements are outlined followed by a discussion of possible problems and solutions for a computationally efficient implementation of a twodimensional spatial optical library for Modelicabased simulation environments.
