The use of airborne laser radar (lidar) to measure wind velocities and to detect turbulence in front of an aircraft in real time can significantly increase fuel efficiency, flight safety, and terminal area capacity. We describe the flight-test result

The Space Interferometer Mission (SIM) demands extremely precise and well-characterized laser metrology gauges (also called beam launchers) to monitor the internal and external optical delay quantities which are required for astrometric measurements.

It has been apparent for more than a decade that the weather-forecast wind speed reaching flight crews in commercial aircraft differs by an average of +/- 15 knots from the wind speed actually experienced during the flight at cruise altitude. We rece
