An object detection and location system (2) includes a sensor array (4) for coupling to a support structure and a processing unit (6, 7, 41). At least one motor (20, 21, 22) rotates first and a second reflectors (12, 16) about an axis (18, 19) parallel to an optical axis of the sensor array, and a light source (8) projects a light beam (9a) toward the first reflector (12), which intercepts and reflects the light beam toward the object when the first reflector is directed toward the object, whereby at a given instant of time the light beam strikes the object and is reflected thereby as a second reflected light beam. The second reflector (16) directs a field of view (5) of the sensor array toward the object at the same instant of time to intercept the second reflected light beam and reflect it toward the sensor array. |
