DEVICE, SYSTEM AND METHOD OF RETRO-MODULATING SAFETY SIGNS

摘要

A traffic safety system (100) may be affiliated with an object to be sen from a distance and may be located within a traffic area. The traffic safety system (100) may comprise a retroreflecting mechanism (1 10), enabling to switch between reflecting mode and non retroreflecting mode at certain frequency, thereby creating a flickering effect. In some embodiments, the retroreflecting mechanism (110) may operated in a retroreflective normally on default mode. The non-reflecting mode may include an absorbing mode, a transmissive mode and/or a dispersive mode.
