Abstract/OtherAbstract:
A novel thermal-light-based ranging scheme utilizing second-order coherence in the time domain is proposed and studied. Such a scheme allows ultrahigh accuracy to be achieved for absolute range measurement. Besides, the scheme has the advantages of high immunity to noise and no measuring dead zone. A proof-of-principle experiment has been done, and the result shows a ±10  cm accuracy at a distance of 1 km, which is currently limited by our detectors. The accuracy can be greatly improved to the nanometer scale by using state-of-the-art detectors with an appropriate data processing algorithm.
