Abstract
Disclosed are method and apparatus for forming multiple images of an object comprising a plurality of depth segments. An optical system comprises an infinity optical subsystem and a multi-image optical subsystem. The infinity optical subsystem is configured to receive light from the object and form a first image focussed at infinity. A multi-image optical subsystem is configured to receive the first image and form multiple images via multiple focussing lenses. Each multiple image can correspond to a different depth segment. A portion of the light from the first image can also be filtered before entering a focussing lens. Multiple images under different filtering conditions, corresponding to different depth segments or to the same depth segment, can be formed.
