Pulsed illumination in a hyperspectral, fluorescence and laser mapping imaging system

An endoscopic system for providing visualization to a light deficient environment comprising:

• an emitter for emitting a plurality of emissions of electromagnetic radiation, wherein the plurality of emissions are a plurality of pulses of electromagnetic radiation;
• an image sensor comprising a pixel array, wherein data is read out from the pixel array corresponding to the plurality of pulses of electromagnetic radiation;
• and
• a processor for performing image signal processing, wherein the processor receives the data from the image sensor and generates a plurality of data frames;
• a controller in electronic communication with the emitter and the image sensor;
• wherein the plurality of emissions of electromagnetic radiation comprises a visible emission of electromagnetic radiation and a spectral emission of electromagnetic radiation for eliciting a spectral response from a tissue, and one or more emission sources comprising:
• a mapping emission comprising electromagnetic radiation for generating laser mapping data;
• or
• a fluorescence emission comprising a fluorescence excitation wavelength of electromagnetic radiation;
• wherein the controller instructs the emitter to adjust a magnitude, a duration, or a magnitude and a duration of the plurality of emissions of electromagnetic radiation emitted by the emitter;
• wherein the plurality of pulses of electromagnetic radiation switch between the visible emission of electromagnetic radiation, the spectral emission, and the one or more emission sources in a pulse cycle pattern;
• and
• wherein the plurality of data frames comprises one or more visible image frames generated from the visible emission of electromagnetic radiation, and one or more exposure frames corresponding to and generated from the spectral emission of electromagnetic radiation and the one or more emission sources.
