摘要： 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.

摘要： A LADAR has adjustable operational parameters to accommodate surveillance of a particular site. The LADAR includes a controller, a laser source governed by the controller to generate a laser beam pulsed at a pulse repetition rate, an optical scanner, a first set of optics, a first drive assembly governed by the controller, a second drive assembly governed by the controller, a light detector, a second set of optics for guiding laser echo pulses, and a processor coupled to the light detector to accommodate surveillance of the particular site.
