f Full-spectrum VNIR and SWIR hyperspectral imager in a single instrument

The best full spectrum solutions currently integrate two separate push-broom hyperspectral cameras, VNIR and SWIR, in a platform where they are mechanically aligned to image the target with two parallel field of views (FOV).lt results in a bulky construction which is prone to misalignment. The biggest issue with two separate FOVs is that pixel registration in the VNIR and SWIR image changes with varying distance to the target. It complicates and retards image processing, particularly in near real-time applications.
