Abstract:
1. A system for de don and location of an object, the system comprising: a sensor array having a plurality of sensor elements and being adapted for coupling to a support structure and to a processing unit first and a second reflecting surfaces configured to rotate about an axis of rotation; at least one motor for rotating the first reflecting surface and the second reflecting surface about said axis of rotation; and a light source for projecting a light beam along an optical path toward the first reflecting surface; said first reflecting surface being configured to intercept said fight beam and to reflect the light beam as a first reflected light beam, directed toward said object when the first reflecting surface 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; said second reflecting surface being configured to direct a field of view of the sensor array toward the object at said instant of time so as to intercept the second reflected light beam and to reflect the second reflected fight beam toward the sensor array; and the sensor array being attached to a support structure; characterized in that: the sensor array is an area sensor, the light beam is directed in one of; a direction of the sensor array and in a direction opposite to the sensor array, rotation of the first reflecting surface rotates the light beam so as to intersect objects that he in a plane perpendicular to the axis of the shafts, the sensor array is configured to represent the location of the detected object relative to the support structure as a vector, the vector having a vector length and a vector direction, wherein the direction of the object, relative to the sensor array defines the vector direction, and the distance between the object and the sensor array is determinable based on the vector length.
