1. A method for generating a polygonal and conical shaped field of view in an imaging system, comprising:
providing an outer lens element having a polygonal shape with a plurality of edges, each of the edges having a plurality of edge surface angles relative to an optical axis of the imaging system; and
configuring the imaging system to provide a field of view having a polygonal and conical shape matching the plurality of edge surface angles along the edges of the outer lens element to constrain a plurality of chief rays to form the polygonal and conical shaped field of view and correspond to the polygonal shape and the plurality of edge surface angles of the outer lens element.
