  • Patent number: 5652652
    Abstract: Applicant's invention is a method and apparatus for inhibiting laser detection wherein the infrared laser light from a laser gun is absorbed, diffused, and dispersed, hindering the quick response needed for accurate laser readings. The laser detection inhibitor incorporates a rectangular thermoplastic lens panel and a filtering treatment which coats or is infused into the thermoplastic lens panel. The thermoplastic lens panel is suitably formed for placement over a vehicular license plate. The panel is adapted for placement over the license plate. After the panel is sprayed or infused during molding with the filtering treatment, the panel is affixed over the license plate using the existing attachment means for the vehicular license plate. Applicant's invention may also be placed in spray or film form over other reflective vehicular parts. Applicant's invention uniformly covers the license plate absorbing, diffusing, and dispersing infrared laser light and therefore, inhibiting laser detection.
