3D motion tracking optical fiber sensor system using multi-core fiber multi-point FBG!
This is a fiber optic sensing system set suitable for 3D sensing and motion tracking applications from FBGS, which supplies FBG strain and temperature sensors using its unique DTG manufacturing method. By combining a dedicated probe with multi-core fiber that has been processed with multi-point FBG sensors and measurement software, it achieves 3D shape sensing and motion tracking. It calculates the displacement of the detected object or its own movement from disturbances and external forces received at each sensor point of the probe, enabling three-dimensional sensing, motion positioning, and tracking data visualization in animation. The target applications are in the medical and healthcare fields, as well as in robotics, where it demonstrates high utility in procedures and tasks under conditions where the use of cameras or image sensors is particularly challenging, based on real-time detection of events and visualization of states from the acquired data. *DTG manufacturing method: Unlike traditional and existing FBG sensor processing, this method involves processing FBGs in the same process after drawing the optical fiber and applying an outer coating material, eliminating the need for post-processing (such as outer resin stripping or re-coating) after completion, thereby ensuring inherently high reliability. The outer resin is typically ORMOCER or polyimide, and it is also compatible with radiation-resistant specifications.

basic information
Measurement Device: This is an A4-sized integrated device equipped with a high-precision, high-speed spectral module and a broadband light source (wavelength range of 1.5μm) for infrastructure health monitoring similar to FBGS's measurement instruments. It connects to a host computer via USB and is powered by an external DC power supply. The optical port for connecting sensor probes has either 1 or 2 points (LSH/PC connector). It also has an external trigger signal input terminal, allowing for synchronized operation with other devices. The guaranteed operating temperature range is 0 to +45°C. By combining with a dedicated probe and measurement software, a 3D detection and motion tracking system can be constructed. Multi-core Fiber Sensor Probe: Probe length is 1050mm (excluding lead section), detection area length on the probe is 250, 500, or 1000mm (average detection error of 0.87mm or less), outer tube material is nitinol (approximately φ0.4mm, minimum bending radius of 20.5mm), guaranteed operating temperature range is +15 to +50°C. Options: 3D visualization of measurement data, adjustment of probe lead length and detection points, addition of temperature detection functions, etc. We are also open to discussions regarding the integration of this product's probe into your existing device probes.
