Job description

Project Description

In nonimaging optics we study light transfer from a source to a target, to control or optimize photometric quantities like illuminous intensity or illuminance at the target. A well-known simulation method for this is the Monte Carlo ray tracing method. In this method, the propagation of randomly selected rays through an optical system, containing e.g. collimators and/or lenses, is computed. The propagation of a ray can be represented in a two- or four-dimensional phase space and can be interpreted as the flow of a Hamiltionian system. Thus, the map which transforms a source distribution to a target distribution is symplectic.

It is the goal of this project to apply this phase space analysis to optical systems in order to:

  • Have a better understanding of mixing of light and improve optical systems that mix light. In lighting applications several LEDs are used and in many cases these LEDs have different colors. It is necessary to mix the light of these LEDs to get a good uniform light pattern. Using phase space analysis it is possible to come up with new designs that result in improved mixing properties compared to designs we already know. This approach exploits tools developed in non-linear dynamics.
  • Create the optical systems that belong to optical mappings. Using optimal transport theory, we can create optical maps. Based on these optical maps we need to create optical systems that are the physical realisation. Phase space analysis and Hamiltonian descriptions can help us in reaching this goal.
  • Create new optical elements with an improved look and feel. Phase space analysis allows us to understand better how light is transported in an optical system. Based on this knowledge we can create new optical elements that have an improved look and feel and are potentially smaller.

This PhD research will be executed in close cooperation with the world leader in lighting: Philips Lighting. The project is embedded in a cluster of projects related to illumination optics and the candidate is expected to work closely with the other PhD students and to be present several days a week at Philips Lighting. This will allow the candidate to have a strong interaction with the engineers that will use the tools after the project has been finished.

As a PhD student your tasks are the following:

  • Perform scientific research in the described domain;
  • Present results at international conferences;
  • Publish results in scientific journals;
  • Participate in activities of the group and the department;
  • Assist SC-staff in teaching undergraduate and graduate courses (at most 20%of the time).

Requirements
