Traditional imaging methods, which are relatively costly and complex, rely on a lens to focus light onto a sensor that records photons.
The proposed invention uses an image recording device placed at the edges of a transparent layer to accurately reproduce an image. A small fraction of the light from the outside scene scatters off imperfections in the transparent layer to reach the image-recording device. The full scene is reproduced computationally from the point sources. The image is captured without a lens and without a direct line of sight to the scene. While the system could be used to capture any image, it is applicable specifically to biometrics and automotive machine vision.
