Abstract:
An example method and hyperspectral imaging (HSI) system for imaging a scene are provided. The method is for imaging the scene with the HSI system including a sensor with a plurality of sensor pixels and a plurality of spectral filters, each of the spectral filters being associated with one of the sensor pixels. The method comprises obtaining a higher-resolution spatial image by illuminating the scene with a first set of wavelengths, wherein each spectral filter passes the first set of wavelengths to the sensor pixel it is associated with. The method further comprises obtaining a lower-resolution hyperspectral image by illuminating the scene with a second set of wavelengths, wherein each spectral filter passes only a subset of the second set of wavelengths to the sensor pixel it is associated with.
