Hypersperctral remote sensing has two distinct characters that the band number is more than multispectral remote sensing and the width of band is narrow.
The key technique of this new filter is how to achieve the extreme narrowband-pass width and a slight deviation of central frequency.
如何实现极窄的通带宽度和极小的中心频率偏差是研制中所解决的关键技术问题。
