Ecological Systems and Devices Annotation << Back Perspective of development of laser scanners and rangefinders technology in the control problems of industrial and natural objects Grigorevskii V.I. Sadovnikov V.P. Yakovlev Yu.O. An overview of modern technology of laser scanners and range finders application for measuring natural and industrial objects is done in this paper. The technique of phase measurements based on multi-frequency modulation of the laser radiation was proposed, which simplifies a phase ambiguous resolution when measuring large distances to the object. A model of scanning rangefinder allows effective spatial scanning of industrial and natural sites. On the basis of this model, scheme remote geophysical measurements was proposed, which encompasses corner reflectors , with the possibility of using active reflectors. Rangefinder with active reflector increases the range of the device several times. It can be effectively used in geophysical studies of Earth's surface and in control of shear deformations.
