Claim 19:
20. An imaging optical system, comprising:
a first optical sub-system having at least one optical element;
said first optical sub-system being configured to substantially collimate electromagnetic radiation emanating from an object plane;
at least one segmented light bending element;
said at least one segmented light bending element being configured to substantially receive a portion of said electromagnetic radiation from said object plane;
said at least one segmented light bending element comprising a plurality of segments, each segment in said plurality of segments being configured to direct a portion of electromagnetic radiation from said first optical sub-system in a plurality of portions along a direction in a plurality of directions; wherein each direction in said plurality of directions is substantially different from other directions in said plurality of directions;
a second optical sub-system having at least one optical element, said second optical sub-system being configured to substantially receive said plurality of portions of said electromagnetic radiation directed in said plurality of directions;
an image plane;
said second optical sub-system being configured to substantially focus said plurality of portions of electromagnetic radiation directed in said plurality of directions onto said image plane;
at least one segmented light separating element; and
said at least one segmented light separating element comprising a plurality of segments, each segment in said plurality of segments being configured to substantially receive at least one portion of said plurality of portions of electromagnetic radiation directed in said plurality of directions.
