- Experimental Method to Find the Optimum Excitation Waveform to Quench Mechanical Resonances of Fabry–Pérot Tunable Filters Used in Swept SourcesPublication . Trifanov, I.; Bradu, A.; Neagu, L.; Guerreiro, P.; Lobo Ribeiro, Antonio B.; Podoleanu, A. Gh.We report experimental evidence of improving the nonlinearity of conventional wavelength swept laser sources based on a fiber Fabry–Pérot tunable filter as a wavelength-selective element. Our solution is based on applying a nonsinusoidal, synthesized waveform to the tunable filter that can be identified experimentally. A significant improvement in the optical coher- ence tomography image quality has been obtained without any software recalibration method.
