Abstract

The traditional laser ranging technology, due to its superior directivity, monochromism and coherence, have been widely used in the precision measurement of absolute distance. However, Laser ranging with large size and high precision is susceptible to noise interference, and the measurement instrument lacks sufficient stability. In this paper, a non-optical interferometry has been proposed to measure 100 meters absolute distance. Moreover, a laser polarization controlling method, a laser frequency scanning technique and a heterodyne detector are designed to enhance laser feedback ranging signal and improve the low-frequency noise. The proposed study will serve as a valuable reference for large size and high precision absolute distance measurement.
