Abstract

One example system includes a lens disposed relative to a scene and configured to focus light from the scene. The system also includes an opaque material. The opaque material defines a plurality of apertures including a primary aperture and one or more secondary apertures. The system also includes one or more light detectors (e.g., a single element detector or an array of detectors) configured to intercept and detect diverging light focused by the lens and transmitted through at least one of the plurality of apertures defined by the opaque material.
