Short Range Shape Sensing Repeatability and Drift:
Repeatability of the endpoint measurement on a 2.5m shape sensor was tested over 16.5 hours on a system running at 10Hz. The endpoint standard deviation (3D position) was measured to be σ = 1.6mm (0.06% by length), or 3σ = 5.0mm (0.2% by length). A histogram of the measurement is shown below in Figure 2.
