Abstract
The detection of reflective interfaces in a multilayer object using Coherence Radar [1] is limited by the dynamic range of the analogue CCD camera and the analogue to digital (A/D) converter or frame grabber [2]. In this paper, we describe a new differential detection method for Coherence Radar which significantly reduces the required dynamic range of the A/D converter.
