摘要： Combined laser-based apparatus for determining both altitude and ground velocity of an aircraft comprises: a laser source for emitting pulsed laser beams substantially at a predetermined wavelength; a plurality of first optical elements for directing the laser beams from a first optical path to a second optical path which exits the first optical elements; a plurality of second optical elements configured to form a telescope, the second optical path and telescope field of view being fixedly co-aligned; an optical scanner for directing the second optical path and telescope field of view to desired ground positions while maintaining the co-alignment thereof; the telescope for receiving Doppler wavelength shifted reflections of the pulsed laser beams and directing the received ground reflections substantially over a third optical path; an optical filter element for separating the ground reflections of the third optical path into first and second portions that are dependent on the Doppler wavelength shift of the ground reflections; and processing means for determining altitude and ground velocity of the aircraft based on the first and second portions.

摘要： A laser transmitting system includes a laser source configured to transmit a laser beam at an original transmit intensity. The system also includes a laser intensity adjusting mechanism positioned in the path of the transmitted laser beam. The laser intensity adjusting mechanism is controllable to reduce the intensity of the laser beam from the original transmit intensity. The system also includes a controller coupled to the laser intensity adjusting mechanism. The controller is configured to automatically control the laser intensity adjusting mechanism based upon a safety criteria. Methods of controlling a laser transmitting system are also provided.
