Abstract
(EN)
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.

Un exemple de système comprend une lentille disposée par rapport à une scène et conçue pour focaliser la lumière provenant de la scène. Le système comprend également un matériau opaque. Le matériau opaque définit une pluralité d'ouvertures comprenant une ouverture primaire et une ou plusieurs ouverture(s) secondaire(s). Le système comprend également un ou plusieurs détecteur(s) de lumière (par exemple, un détecteur à élément unique ou un réseau de détecteurs) configuré(s) pour intercepter et détecter une lumière divergente focalisée par la lentille et transmise à travers au moins l'une de la pluralité d'ouvertures définies par le matériau opaque.
