Extraction of vibration parameters from optical feedback interferometry signals using wavelets
(2015-12-01)
Article
Accés obertThis paper proposes the use of the wavelet transform as a technique that is suited for fringe detection and analysis of optical feedback interferometry (OFI) signals, thus allowing the retrieval of extremely small physical ... -
Frequency-Modulated Optical Feedback Interferometry for Nanometric Scale Vibrometry
(2016-02-18)
Article
Accés obertWe demonstrate a novel method that makes an efficient use of laser nonlinear dynamics when subject to optical self-injection for subwavelength displacement sensing purposes. The proposed methodology combines two different ...
