Abstract

This article presents a new robust, precise, high-frequency
focal-distance-modulated confocal point sensor for probing in coordinate
measuring systems (CMSs). While maintaining the known advantages of the
confocal measurement principle, the sensor represents an innovative
combination of a fiber-coupled confocal illumination and detection with a
tuneable, acoustically driven gradient-index fluid lens for modulation
of the focus distance and a novel signal processing utilizing a lock-in
amplifier. The new arrangement is able to achieve an approximately
linear characteristic curve for the optimized feedback control of the
CMS in scanning sample mode. This article emphasizes the optical
application and the signal processing of the setup.
