Abstract
An active laser guarding systemcomprises at least one screenprovided with at least two spaced apart conductorseach defining a respective electrically conductive path that is electrically separate from the other. The screencomprises material, at least between the two conductors, which is arranged to carbonize when struck by a laser beam to form a further conductive pathwhich extends between, and electrically connects, the two conductors. The systemfurther comprises a detectoroperative to detect the further conductive pathso formed, the detectorbeing operative to generate a laser deactivation signal response to detecting the further conductive path
