Popular Illumination Software Extends Modeling And Analysis Features

By Mat Dirjish

Version 9.0 of LightTools, Synopsys’ illumination design software, adds modeling and analysis features that augment LightTools’ established design capabilities, reliability, and accuracy. The added tools to model and analyze polarizing elements with birefringent materials are necessary for emerging applications such as augmented and virtual reality headsets and biomedical instruments.

Additional charts allow designers to assess polarization states and orientations and identify how to maximize flux. Additional polarization modeling tools in the LightTools Advanced Physics Module provide programming extensions to develop custom optical parts and unique illumination subsystems.

Enhancements to the LightTools stray light analysis toolkit include:

  • Intense ray tracing: LightTools now traces up to one trillion rays in an illumination system, lifting the sampling limits for virtually all Monte Carlo simulations. This wider ray trace limit allows designers to achieve extremely accurate results for straylight analysis and luminance calculations.
  • Aim area capabilities for measuring bidirectional scattering distribution function (BSDF) surfaces: BSDF data provides high-accuracy simulations of scattering surface characteristics. The aim area feature allows designers to examine portions of a surface’s scatter distribution. Reportedly, this can significantly improve stray light analysis efficiency, particularly for illumination optics used in AR/VR/MR devices, heads-up displays, and autonomous vehicles.
