    LumiConSense: A Transparent, Flexible, Scalable, and Disposable Image Sensor Using Thin-Film Luminescent Concentrators

Description:


    Our 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 in longer wavelengths, while wavelengths outside the sub-band are fully transmitted. The example shown in figure 1(a) absorbs blue and emits green light. The emitted light is mostly trapped inside the film by total internal reflection (TIR), and is transported with reduced multi-scattering towards the LC edges while losing energy over transport distance. The bright film edges indicate decoupling of the light integral transported to each edge point from all directions inside the LC.
