Airborne die laser offset distance instrumentation system

摘要

PROBLEM TO BE SOLVED: To thoroughly measure information on position of an object located below an aircraft in its advancing direction and further to record information on the outside air temperature during measurement at the same time. ;SOLUTION: The laser distance measuring device 11 is provided with first to n-th lasers 21-1 to 21-n and first to n-th detectors 22-1 to 22-n provided correspondingly to the lasers 21-1 to 21-n. n sets of laser and detector are prepared, and the sets of each pair of laser and detector have various visual fields respectively to the advancing direction of aircraft, and they are fitted to entirely cover the field below the aircraft in its advancing direction. In addition, the lasers 21-1 to 21-n emit laser lights at the same time.;COPYRIGHT: (C)1998,JPO
