1. A system, comprising:

a lens disposed relative to a scene, wherein the lens is configured to focus light from the scene;

an opaque material, wherein the opaque material defines a plurality of apertures;

an array of light detectors; and

a microelectromechanical system configured to select an aperture from the plurality of apertures such that the light from the scene focused by the lens is directed to the array of light detectors via the selected aperture.
