【Abstract】 An absolute range measuring system that can separate the target locating process from the measuring process is proposed in the paper. The introduction of optic fiber interferometry to the system improves its flexibility and anti interference capacity. The multiplying of the measuring stroke and the enlargement of the system measuring range are realized by means of the optic fiber group that has been accurately scaled. The basic principle and a processing system for digital locating signals is described, the corresponding experimental results are also given.更多还原
