Patent ID: 8080795

Claim:
A device for imaging the local distribution of at least one thermodynamic variable comprising: a radiation emitter capable of emitting electromagnetic radiation, and a filter for filtering electromagnetic radiation, the emitter and the filter forming an arrangement adapted for modifying the electromagnetic radiation emitted by the emitter in dependency of the local distribution of at least one thermodynamic variable at the location of the arrangement, wherein the emitter comprises at least one electroluminescent layer, the filter comprises at least one filter layer, and the electroluminescent layer and the filter layer are integrated within a cohesive sequence of layers, and wherein the filter comprises an array of filter elements the radiation emitter comprises a plurality of emitter elements and wherein the emitter elements and the filter elements are respectively integrated into stacks of layers mounted on a substrate, each stack forming a pixel for imaging the local distribution of the at least one thermodynamic variable.
