Piezo-actuated tunable microlenses are also of great interest in various miniaturized systems. In this seminar, I will illustrate the functionality of laser diode feedback interferometry, or self-mixing interferometry, for analyzing the out-of-plane vibration performance of a commercial piezo-MEMS speaker, showing the advantages with respect to a classical Michelson scheme. Characterization of the quasi-static behavior of a tunable microlens by means of low-coherence interferometry will be illustrated, as another example of application of spot-optical techniques for MEMS testing.<\/div>\n<div class=\"x_elementToProof\" data-ogsc=\"rgb(0, 0, 0)\"><span data-ogsc=\"\" data-ogsb=\"rgb(255, 255, 255)\"><b data-ogsc=\"\"><br \/>\nSpeaker&#8217;s bio<\/b><\/span><\/div>\n<div class=\"x_elementToProof\" data-ogsc=\"rgb(0, 0, 0)\"><span data-ogsc=\"\">Sabina Merlo received in 1987 the master\u2019s degree and in 1991 the Ph.D. degree, both in electronic engineering, from the University of Pavia.
