The hyperspectral detector systems and methods disclosed herein include capturing a context image and a single-column spectral image that falls within the context image. The context and spectral images are then combined to form a fused image. Using the fused image, the spectral image is panned over the scene and within the context image to capture spectral signatures within the scene. The spectral signatures are compared to reference spectral signatures, and the locations of the one or more spectral signatures within the context image are marked. The systems and methods obviate the need to store and process large amounts of spectral data and allow for real-time display of the fused context image and spectral image, along with the marked locations of matched spectral signatures.
