Optics

The Noumenon team has over 8 years of experience in modeling diverse optical phenomena, garnered from our work on electro-optical devices, solar optics, lenticular lenses, radiative transfer and other optics applications.

With over 24 combined years of experience in optical modeling and simulation, we have experience modeling many optical phenomena, including:

  • Geometric Optics
  • Wave Optics & Electromagnetics
  • Mie Scattering
  • Solar Optics
  • Lenticular Optics & Lens Design
  • Imaging & Non-imaging Optical Sensing
  • Photoluminescence
  • Bulk Radiative Transfer
  • Quasimonochromatic Light (Stokes/Mueller Calculus)
  • Birefringence
  • Non-imaging Optics

We have applied this expertise to applications in diverse industries such as:

  • Displays
  • Solar Energy
  • Photosynthetic Applications
  • Image Sensors
  • Automotive Lighting
  • Entertainment
  • Architectural Lighting
  • Street Lighting
  • LEDs
  • Biomedical Devices
  • Photometry
  • Industrial Sensing & Quality Control

Projects

Following are some interesting optics-related modeling and simulation projects that we have performed in the past:

MONTE-CARLO RAY TRACER. In this project, we built a generalized Monte-Carlo integration based light transport solver. The ray tracer can solve any problem involving light transport, geometric optics, media with indexes, mirrors, absorbers, etc. Read more…

LENTICULAR OPTICS. We built a linear feedback theory based lenticular geometric optics solver, which was much faster than a generalized ray tracer can be. Read more…

LIGHT TRANSPORT. An integro-PDE equation was proposed for a class of light transport problems involving light guides made of bulk scattering material. The equation features not three but five geometric dimensions, three in differential and two in integral form. The integral form can be imagined to be a “spherical integration” — i.e. a linear shift invariant system where “shift” is defined using the symmetry group of a sphere. Read more…

SOLAR OPTICS. This simulator framework can calculate the position of the sun for any day of the year, and time of day, at any latitude. Furthermore, the simulator can calculate various shadowing effects applicable to objects such as heliostats (sun tracking mirrors). Averages of shadowing effects over time can be used to optimize placement, size etc. of these objects to maximize utilization of insolation.

BIREFRINGENCE. Created models of uniaxial and biaxial birefringence. The biaxial birefringence model requires a modal decomposition of a non-linear equation, which was solved using a novel non-linear Rayleigh quotient method devised by us. These models were used to find birefringence parameters of actual samples. Read more…

OPTICAL SENSOR NON-LINEARITY. We have created multiple techniques of detecting and removing non-linearity of optical sensors. In one technique, non-linearity of a CCD or CMOS sensor can be measured and corrected using just two photographs of a same scene, at two different exposure levels.

ELECTROMAGNETIC FEM. Built our own FEM EM solver to cross-check Mie scattering calculations, and to be able to perform scattering calculations for irregular shaped objects.
