Abstract
A system and method for performing field measurement and testing of a plurality of widely spaced laser beams used in visual warning technology (VWT). VWT uses a combination of widely spaced laser beams, to warn civilians from approaching too close to military security areas. The widely spaced laser beams are displaced using rhomboidal prisms. Each rhomboidal prism receives a corresponding laser beam and displaces it toward a collecting lens. The lens focuses the displaced beams received thereon onto an imaging sensor for testing. Beam shutters may be used for selectively blocking one or more beams in order to test the beams separately and in different combinations.
