Abstract
A probe, system, and method of capacitive sensing for detection of relative rotation of one tube with respect to a fixed tube of a probe is provided herewith. The probe includes an inner core, a concentric cylindrical tube, and at least one inner electrode fixed to the inner core and at least one outer electrode fixed to the cylindrical tube. The electrodes are rotationally aligned and form a capacitive sensor that can sense the rotation angle of the inner core compared to the cylindrical tube. This ability to sense relative rotation angle can be used to detect and/or correct for non-uniform rotational distortion.
