Single-Multi-Single Fibre Optic Structure Based Water Depth Sensor
Garima Bawa, Krishnendu Dandapat, Gyanendra Kumar +2
We propose and demonstrate a technique easy to fabricate and measure water depth based on selective mode excitation using single-multi-single (SMS) mode structure. The high extinct…
