In this paper, we propose a noncontact and absolute type displacement sensor detecting multiple targets using standing wave on a transmission line. The standing wave is generated, when driving the transmission line by a high-frequency signal toward the targets, due to additive-synthesis from the drive-signal and the reflected signals induced by the targets. The level of the synthetic signal observed at a certain point on the transmission line, periodically changes with the frequency of the drive-signal. Namely, the observable signal level is a sinusoidal function of the frequency. Besides, the period is inverse proportional to the displacement of each target with reference to the observation point. Thereby, we propose a method to find the period by Fourier Transforming.<br>We have confirmed experimentally that each target can be detected individually in the displacement from 0.2m to 3.6m and the resolution of 0.5mm is feasible.
