The parallel light beams (130) assist in producing a light pattern on a target site. A method of measuring a dimension of a target site includes the steps of projecting uniformly spaced parallel light beams (130) to form a light pattern having uniformly spaced elements on the target site, aligning the light pattern (140) such that a maximum number of the uniformly spaced elements is positioned along the dimension and counting the maximum number of the uniformly spaced elements positioned along the dimension.1/3 102 110 130 100 / ........ gtodx - x.......dx 140 FIG. 1 110 102a 130 C: ----- ---------- --S.....- - 140a 120a2 FIG.3 110 102a 130 C --- --- ------ -- - -- - 140b 120b FIG. 4
