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 filter mosaic of various bands with narrow spectral width can be achieved with single run manufacturing processes (i.e., exposure, development, deposition, and other minor steps) regardless of the number of bands.

用于多光谱成像的混合彩色滤光片

多光谱相机在狭窄的光谱带中捕获多个波长的图像。它们提供了远远超出普通相机的先进传感功能，并且许多基于单传感器的多光谱相机已针对多种应用进行了商业化，例如农林业研究，医学分析等。但是，现有的基于单传感器的多光谱相机需要精确对准，以将每个滤镜覆盖在图像传感器像素上，这使得其制造非常复杂，尤其是在波段数很大时。本文通过计算仿真演示了一种使用单等离激元层和介电层的混合组合的新滤波器技术。通过单次运行制造过程（即曝光，显影，沉积，
