Imaging zoom for wide field-of-view imaging spectrometer

An imaging system comprising:

• a wide field of view (FOV) telescope configured to produce a one-dimensional optical image of a broad FOV F;
• a narrow FOV telescope configured to produce a two-dimensional optical image of a narrow FOV f;
• a spectrometer configured to produce a spectrum of a one-dimensional image;
• an imaging detector configured to capture the spectrum;
• an image slicer configured to break the two-dimensional optical image into a series of one-dimensional segments
• an image processing block configured to identify and categorize features of the captured spectrum;
• a point of interest (PoI) detection block configured to identify PoIs within broad FOV F based on features identified and categorized by the image processing block;
• a slew control block configured to direct narrow FOVf to PoIs identified by the PoI detection block;
• and
• a selection mechanism operable in either of two modes:
• a wide FOV mode transmitting the one-dimensional optical image to the spectrometer, and a zoom mode transmitting a one-dimensional concatenation of the series of one-dimensional segments to the spectrometer.
