ABSTRACT
Conventional optoelectronic techniques have forced image sensors to a planar shape. We present our first attempts towards a transparent, flexible, scalable, and disposable sensor that samples the light-transport of a two-dimensional light-field within a thin-film luminescent concentrator for reconstructing an image being focussed on the concentrator film.

LumiConSense: a transparent, flexible, scalable, and disposable image sensor using thin-film luminescent concentrators
SIGGRAPH '14: ACM SIGGRAPH 2014 Emerging TechnologiesOur sensor [Koppelhuber and Bimber 2013] consists of a thin, transparent polycarbonate film, referred to as luminescent concentrator (LC), that is doped with fluorescent dyes. Light of a particular wavelength sub-band that penetrates the film is emitted ...
Shield fields: modeling and capturing 3D occluders
We describe a unified representation of occluders in light transport and photography using shield fields: the 4D attenuation function which acts on any light field incident on an occluder. Our key theoretical result is that shield fields can be used to ...
An image sensor based on optical Radon transform
This paper summarizes our progress towards a first fully transparent, flexible, scalable, and disposable thin-film image sensor. In contrast to conventional image sensors, it does not capture pixels in image space on the sensor surface, but makes ...
