IEEE Sensors Journal
Year: 2024 | Volume: 24, Issue: 2 | Journal Article |
Cited by: Papers (5)
Trifurcated optical fiber displacement sensors (OFDSs) are increasingly used in industrial and aerospace applications. The critical element of the sensor is the fiber bundle. However, there is no straightforward method to calculate it from the working specifications of the sensor, the number of fibers needed, their size, and arrangement. This work presents a simple yet accurate method to design tr...Show More
