Implementation of differential self-mixing interferometry systems for the detection of nanometric vibrations
23/07/2018
Last Friday, July 20, 2018, at the Joan Salvadó Auditorium of the University Center of Vision, Francisco Javier Azcona Guerrero defended his doctoral thesis entitled "Implementation of differential self-mixing Interferometry systems for the detection of nanometric vibrations".
The thesis has been supervised by Dr. Santiago Royo Royo, CD6 Director.
In the thesis is reported a technique called Differential Self-Mixing Interferometry through which it is possible to determine the displacement of vibrations with amplitudes less than λ/2 (400nm for NIR lasers) with a high resolution (λ/100). In combination with classical SMI it is possible to use the technique in a wide variety of applications ranging from biomedical measurements (eg. arterial pulse wave) to scientific applications (eg. vibration detection of cantilevers as used in AFM).
