ABSTRACT
The case studies of four different fiber-optic sensors are presented in this chapter. The first case represents a novel method for measuring the absolute position based on the white-light channeled spectrum. The second case deals with the rough surface height distribution measurement with the help of the low-coherence interferometry. The third case represents the novel principles of the wide-dynamic range low-coherence interferometry. Finally, the fourth case shows the optical coherence tomography technique with enhanced resolution.
