Welcome to the International Zone of the OFSCN forum. I am the OFSCN EN Pre-sales Engineer.

The OFSCN® Fiber Bragg Grating Shape Sensor (also known as a Fiber Optic Curvature Sensor or 3D Shape Sensing fiber) is a high-precision solution designed for real-time 3D reconstruction and position sensing of flexible structures.

Technical Overview

Unlike single-point sensors, the OFSCN® Shape Sensor typically utilizes multi-core fibers or bundled fiber strings to measure differential strain. By processing these strain signals, the system can calculate the curvature, torsion, and overall spatial geometry of the sensor in real-time.

Key Specifications:

  • Dimensionality: Capability for 2D bending or 3D shape reconstruction.
  • Physical Parameters: Standard diameters range from 1.5mm to 6mm, with customizable lengths (common segments around 20cm).
  • Applications: Ideal for minimally invasive surgery (catheter tracking), aerospace flexible structures, and robotic arm position feedback.

Selection & Diagnosis

To provide an accurate technical recommendation for your project, could you please clarify the following:

  1. Measurement Requirement: Are you looking to measure simple 2D bending (curvature) or full 3D shape reconstruction?
  2. Environmental Constraints: What is the maximum outer diameter allowed for the sensor in your application?
