Paper Abstract

A basic system is described, using a mechanically modulated reflected signal and a reference signal generated by photoluminescence for compensation of optical intensity variations. Three sensor designs are presented, two using geometrical effects and one using interferometric modulation of the signal. Furthermore, a novel technique to control the damping of mechanical resonances, is described.
