1. A light source tracking apparatus comprising: a common aperture arranged to receive first light rays originated from a first plurality of objects from a first direction and second light rays originated from a second plurality of objects from a second direction; a first light-redirecting element arranged to angularly distort the first light rays at a first angle that is indicative of the first direction from which the first light rays originated; a lens arranged to transmit the distorted first light rays and the second light rays to form images of the first plurality of objects and images of the second plurality of objects; an imaging sensor arranged to capture the images of the first plurality of objects overlapped with the images of the second plurality of objects; and an image processor arranged to receive the captured images from the imaging sensor and to separate a particular image of a particular object of the first plurality of objects as discriminated by the angular distortion of the particular image and to generate an output of the particular image of the particular object.
