Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for simultaneously forming multiple images of an object comprising a plurality of depth segments, the method comprising the steps of: receiving light from the object and forming a first image focussed at infinity; filtering a first portion of the first image; receiving the filtered first portion of the first image at a first focussing lens and forming a second image on an image plane, wherein: the first focussing lens has a first focal le…
