I was a bit confused at first because spectral imaging is foundational in astronomy... so that part can't be the breakthrough. I think what makes it "hyper" is when the spectral resolution is high enough that a separate spectrum is obtained for each pixel of the image.
I found the paper published in Nature:
Sounds like the advance here is the sheer bandwidth of data being processed: high frame rate, high resolution, and high spectral detail. They suggest "drone-based anti-vibration video-rate HSI" which at first I thought meant military use, but scientific disciplines also use this capability. For example, the wikipedia article mentions using HSI from drones in order to catch disease outbreaks in grape crops before it spreads.
yeah, this is the really relevant bit:
hyperspectral imaging isn't new, the breakthrough is in combining it with motion video in a way that the information you're getting with the spectral scan gets assigned correctly to objects within a moving scene, which is really interesting. sounds like it partly depends on new hardware:
