Image fusion is a critical issue for remote sensing, and many algorithms have been developed. Image quality assessment of fused image might provide comparison between fusion methods, but the conclusio...
Extraordinarily high spectral sensitivity in refractive index sensors using multiple optical modes
Sensors Surface plasmons Resonators
2015/8/10
The extraordinary spectral sensitivity of surface plasmon resonance (SPR) sensors is commonly attributed to the modal overlap or unique dispersion of surface plasmons. In contrast to this belief, we s...
