Abstract: A light detection and ranging system includes a mirror unit rotating around a scan axis. The mirror unit includes a receiving portion and a transmitting portion offset by an angle about the scan axis relative to a surface plane of the receiving portion. Respective centroids of the receiving and transmitting portions are positioned at a common point on the scan axis while the receiving and transmitting portions rotate around the scan axis. A transmitter transmits a light pulse toward the mirror unit. The transmitting portion is positioned to reflect the light pulse toward a target. A receiver is positioned to reflect the light pulse reflected from the target toward the receiver. The angle offset compensates for a change between a cone of illumination of the transmitting portion and a field-of-view of the receiving portion resulting from the rotation of the mirror unit.

Abstract: A method and system are provided for authenticating a potential threat detected in a perimeter zone of a target site. The method comprises the steps of: detecting a potential threat in the perimeter zone of the target site; upon detection, interrogating said potential threat for a response by a wireless transmission; declaring the potential threat unauthorised if no response is transmitted wirelessly within a predetermined time interval from said interrogation; receiving said response if transmitted, and determining if the response comprises a proper access code; and declaring the potential threat unauthorised if the received response is determined not to comprise a proper access code.
