Adaptive autofocus technique for speckle control in optical feedback interferometry
(2014-09-01)
Article
Accés restringit per política de l'editorialAn adaptive autofocus technique for the control of speckle effect in optical feedback interferometry (OFI) is discussed. The beam spot size effect over the OFI signal is presented, justifying the proposed approach. An ... -
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 ...
