摘要
An angle-stable, miniaturized and integrate-able imaging system based on plasmon resonances or dielectric resonances for multispectral imaging maintaining full spatial resolution of the image sensor. Active tunability of the filter allows color recording, estimation of unknown spectra and determination of spectral singularities, for example laser lines, with the use of a conventional B/W camera. The system is characterized by high angular acceptance, cost-efficient fabrication and ease-of-use. This system can be used in conjunction with other commercial multispectral imaging systems such as RGB cameras to further enhance the spectral resolution. It can be adapted to different spectral ranges, depending on the application.
