Low coherence interferometry (LCI) is a well-known measurement technique able to provide an axial precision in the order of the microns. Its application to a wide variety of fields like medicine has attracted the interest of many authors mainly due to its non-invasive characteristic. By combining LCI and microwave photonics (MWP), we take profit from the inherent stability that the RF domain offers...
In this paper, by means of a well-established parallelism between MWP and LCI, a novel MWP-LCI technique is proposed and experimentally evaluated. This technique is based on the slicing of a broadband source which is transmitted through a dispersive element. The optical path differences (OPD) under test modifies the electrical transfer function of the MWP-LCI subsystem through a interferometric structure...
