| 1. A method, comprising:
imaging a volume through a plurality of image apertures, arranged in a specified arrangement forming a geometric shape with
3 or more points such that object points in the volume are each imaged on at least one two dimensional image sensor as three
or more corresponding image points, each image point corresponding to the object point and to one of the plurality of image
apertures and the corresponding image points being arranged in a pattern geometrically similar to the geometric shape in which
the image apertures are arranged; and
determining information about a location of the object points in the volume using geometrical information based upon the location
of each of the image points corresponding to each object point on the at least one two dimensional image sensor wherein said
determining identifies the image points corresponding to an object point by finding the pattern geometrically similar to the
geometric shape in which the image apertures are arranged.
