Apparatuses, systems, and methods for led-based hyperspectral imaging

A hyperspectral imaging system comprising:

• an illumination unit comprising:
• a plurality of LEDs configured to emit light comprising at least one spectral band;
• and
• a first optical assembly configured to receive the light from the plurality of LEDs and output a light beam comprising the at least one spectral band to illuminate a target region of an imaging subject;
• an imaging unit comprising:
• a second optical assembly configured to collect light reflected from the target region and direct the collected light to an image sensor;
• and
• an image sensor configured to capture an image of the target region;
• a control unit in communication with the illumination unit and the imaging unit, the control unit comprising at least one processor and a non-transitory storage medium storing instructions that, when executed by the at least one processor, cause the system to perform operations comprising:
• activating at least one LED of the plurality of LEDs based on an activation pattern, wherein the activation pattern comprises a time sequence of selections of one or more LEDs;
• and
• synchronizing the image capture of the target region and the illumination of the target region by coordinating exposure timing of the image sensor and the activation of the at least one LED.
