Formatted abstract A self-mixing laser diode vibrometer including an adaptive optical element in the form of a liquid lens (LL)
has been implemented and its benefits demonstrated. The LL arrangement is able to control the feedback
level of the self-mixing phenomenon, keeping it in the moderate feedback regime, particularly suitable for
displacement measurements. This control capability has enabled a remarkable increase in the sensor-totarget
distance range where measurements are feasible. Target vibration signal reconstructions present a
maximum error of  λ/16 as compared with a commercial sensor, thus providing an improved working range
of 6.5 cm to 265 cm. © 2010 Optical Society of America
