Abstract

This work introduces a precise measurement setup for displacement analysis in the near field of a tapered slot-line antenna from 0mm up to 20mm distance. Enhanced accuracy is achieved by a dedicated spiral reconstruction algorithm accounting for the near field effects. Moreover, the precision of the system in the micrometer range is guaranteed by four synchronous 24 bit analog-to-digital converters and a decimation factor of 10, leading to an overall update rate of 1 kHz.
