Hyperspectral imaging in a light deficient environment

An endoscopic system for use in a light deficient environment, the system comprising:

• an endoscope;
• an image sensor comprising a pixel array that detects electromagnetic radiation and reads out image data;
• and
• an emitter comprising a plurality of sources of electromagnetic radiation that emit a plurality of pulses of electromagnetic radiation, wherein the plurality of sources comprises:
• a plurality of hyperspectral sources of electromagnetic radiation, and
• a secondary source of electromagnetic radiation comprising one or more of:
• a visible source of electromagnetic radiation,
• a fluorescent excitation source of electromagnetic radiation, and
• a mapping source of electromagnetic radiation;
• and
• a controller that is in communication with the image sensor and the emitter, wherein the controller is configured to synchronize operation of the image sensor and the emitter;
• wherein the controller instructs the emitter to pulse within a plurality of frame periods of the image sensor;
• wherein the emitter pulses the two or more hyperspectral sources of the plurality of hyperspectral sources of electromagnetic radiation simultaneously for one or more frame periods of the plurality of frame periods;
• wherein the two or more hyperspectral sources of the plurality of hyperspectral sources of electromagnetic radiation each pulse different wavelengths of electromagnetic radiation.
