(1) Background: The classic moiré effect requires grids consisting of multiple lines. However, it is not always possible to have a multi-line grid on an object. (2) Methods: We propose to treat intersecting lines as two single-line grids and process their intersection as the moiré effect. (3) Results: Simulations confirm this. Tests were conducted in the lab and in the field using wires and other long objects. The results are consistent with the theory and previous measurements. (4) Conclusions: The proposed approach allows measurements of single-line displacement, accurate as in moiré methods. Measurements using the intersection of two lines are possible in hard-to-reach and in unreachable locations, as well as when an installation of a multi-line grid could introduce mechanical distortions.
