Full-Range Ultrasensitive Fiber-Optic Hydrogen Detection via Twin Vernier Amplification and Lightweight CNN.
Reliable hydrogen monitoring requires sensors that combine high sensitivity, wide dynamic range, and resistance to environmental interference. Here, we report a monolithically integrated dual-Fabry-Pérot interferometer (dual-FPI) fiber-optic hydrogen sensor that couples twin Vernier spectral amplification with a lightw...
