Abstract

We developed a two-dimensional multispectral imager that exploits the extraordinary optical transmission of nanohole arrays (NHAs) in a metal film for color separation. The NHA device consisted of blocks in a tiled arrangement, where each block contained multiple metallic NHAs, each with unique feature geometry to enable separation of a mixture of colors into distinct spectral bands. The NHA device was integrated into an optical imaging system. The system was used to capture near video-rate images of a scene and then unmix the colors within the scene into 4 spectral bands in the nearinfrared regime.
