A Reconfigurable Camera Add-On for High Dynamic Range, Multispectral, Polarization, and Light-Field Imaging
We propose a non-permanent add-on that enables plenoptic
imaging with standard cameras which we refer to as
KaleidoCamera. Our design is based on a physical copying
mechanism that multiplies a sensor image into a number of
identical copies that still carry the plenoptic information
of interest. Via different optical filters, we can then
recover the desired information. A minor modification of the
design also allows for aperture subsampling and, hence,
light-field imaging. As the filters in our design are
exchangeable, a reconfiguration for different imaging
purposes is possible. We show in a prototype setup that high
dynamic range, multispectral, polarization, and light-field
imaging can be achieved with our design.

Measuring BRDFs of Immersed Materials
In: Proceedings of VMV 2011.
Abstract
We investigate the effect of immersing real-world materials
into media of different refractive indices. We show, that
only some materials follow the Fresnel-governed
behaviour. In reality, many materials exhibit unexpected
effects such as stronger localized highlights or a
significant increase in the glossy reflection due to
microgeometry. In this paper, we propose a new measurement
technique that allows for measuring the BRDFs of materials
that are immersed into different media.
