Paper Abstract

A synthetic type of distance ranging system is described in this paper. In this system, one frequency-modulated laser beam and two multimode laser beams that come from different lasers, having different wave length, are input to a Michelson interferometer together with the same path. When the systems start to run, the computer may send out signals driving the reference reflector to find or keep the zero optical path difference, according to the principle of frequency-modulated ranging and quasi-white light positioning with the interferometer. In the meantime, the shifted value of the reference reflector would be measured by another interferometer. Lastly, the distance can be accurately detected by that value and the environment parameters through calculating with computer. Some fundamental experiments have been done, proving the feasibility of this synthetic method.
