  • Publication number: 20170237918
    Abstract: A light field imaging system with transparent photodetectors is presented. The light field imaging system includes: a stack of two or more detector planes, an imaging optic, and an image processor. The detector planes include one or more transparent photodetectors, such that transparent photodetectors have transparency greater than fifty percent (at one or more wavelengths) while simultaneously exhibiting responsivity greater than one amp per watt. The imaging optic is configured to receive light rays from a scene and refract the light rays towards the stack of two or more detector planes, such that the refracted light rays pass through the transparent detector planes and the refracted light rays are focused within the stack of detector planes. The image processor reconstruct a light field for the scene (at one of more wavelengths) using the light intensity distribution measured by each of the photodetectors.
