A white light interferometric system in sensor applications is often configured with a sensing interferometer to respond to the measurand and a receiving interferometer to recover the signal by means of a scanning system. Mechanical and electronic scans are the two techniques commonly used at present. In this paper, an optical scanning technique is presented as an alternative for sensor use with comparable performance. This technique offers the possibility of eliminating the receiving interferometer and the potential of a simple, stable and compact system.<>
