SYSTEMS AND METHODS FOR REDUCING MEASUREMENT ERROR IN OPTICAL FIBER SHAPE SENSORS |
摘要 |
A shape sensing apparatus comprises an instrument including an elongated shaft with a neutral axis. The shape sensor also includes a first shape sensor with an elongated optical fiber extending within the elongated shaft at a first radial distance from the neutral axis. The apparatus also includes a shape sensor compensation device extending within the elongated shaft and including a temperature sensor. The apparatus also comprises a tracking system for receiving shape data from the first shape sensor and compensating data from the shape sensor compensation device for use in calculating a bend measurement for the instrument. |
