University of Linz Lensless Camera

University of Linz, Austria, publishes a paper "Thin-film camera using luminescent concentrators and an optical Söller collimator" by Alexander Koppelhuber and Oliver Bimber.

"We discuss optical imaging capabilities and limitations, and present first prototypes and results. Modern 3D laser lithography and deep X-ray lithography support the manufacturing of extremely fine collimator structures that pave the way for flexible and scalable thin-film cameras that are far thinner than 1 mm (including optical imaging and color sensor layers)."
