Abstract
An image sensor configured to resolve intensity and polarization has multiple pixels each having a single microlens adapted to focus light on a central photodiode surrounded by at least a first, a second, a third, and a fourth peripheral photodiodes, where a first polarizer at a first angle is disposed upon the first peripheral photodiode, a third polarizer at a third angle is disposed upon the third peripheral photodiode, a second polarizer at a second angle is disposed upon the second peripheral photodiode, and a fourth polarizer at a fourth angle is disposed upon the fourth peripheral photodiode, the first, second, third, and fourth angles being different. In embodiments, 4 or 8 peripheral photodiodes are provided, and in an embodiment the polarizers are parts of an octagonal polarizer.
