Abstract
Multispectral cameras capture images in multiple wavelengths in narrow spectral bands. They offer advanced sensing well beyond normal cameras and many single-sensor-based multispectral cameras are commercialized aimed at a broad range of applications, such as agroforestry research, medical analysis, and so on. However, the existing single-sensor-based multispectral cameras require accurate alignment to overlay each filter on image sensor pixels, which makes their fabrication very complex, especially when the number of bands is large. This paper demonstrates a new filter technology using a hybrid combination of single plasmonic layer and dielectric layers by computational simulations. A filte..
