Light shaping problems such as computer generated holography, beam shaping and illumination design, are concerned with redirecting the light emitted by one or multiple sources into a desired light distribution at a target plane. This is generally achieved using diffractive optical elements, spatial light modulators or freeform optics. However, the methods shaping these optical systems are often limited to simple single-source configurations the most common being: normal incident plane waves. This limits the possible addition of extra sources, thus limiting the total light throughput of the system. As such, it is desirable to extend existing methods to be compatible with more general source configurations.

Objective

We focus on extending existing methods with a pre-processing step making it possible to use more general lighting configuration. This is achieved by determining the effect of source position on the obtained light distribution. Which in turn allows us to alter the light shaping system for optimal performance under the predefined lighting configuration.

Impact

The results of this research can be used to better control the light of street and indoor lighting and used in augmented and virtual reality systems.
