Airborne, continuous-wave modulated neon-helium laser profiler, recently field-tested is accurate to about 1 in. from altitude of 1000 ft at aircraft speed of 240 mph; detail of such profiles remains sharp at altitudes 3 to 5 times greater; laser application is expected to lend greater accuracy to photogeology, gravity work, topographic and pipe line right-of-way surveys, and to aid in emergency landings of aircraft.
