Paper Abstract

Spectral imaging technology is an imaging technique based on narrowband spectroscopy developed in the 1980s. The spectral imager can simultaneously acquire the image information and spectral information of the target, and then accurately measure and analyze the composition of the substance. From food production to environmental monitoring, from material analysis to clinical diagnosis, from industrial monitoring to aerospace remote sensing, imaging spectrometers have become an important means for humans to obtain information, and there is a growing demand for civilian and military applications. It develops toward more spectral channels, higher integration, smaller size, and lighter weight. In this paper, the development methods and development status of several multi-channel spectral filters commonly used at home and abroad, as well as the research results of gradient filter design with half bandwidth of 10 nm in the 400nm~900nm band are introduced in detail.
