1. A system comprising:
an endoscope;
a handpiece unit;
an emitter for emitting pulses of electromagnetic radiation, comprising a plurality of electromagnetic sources, the sources comprising:
a visible source for pulsing a visible wavelength of electromagnetic radiation, and
a specialty source comprising a mapping source and one or more of:
a fluorescence source for pulsing a fluorescence excitation wavelength of electromagnetic radiation, or
a spectral source for pulsing electromagnetic radiation within a waveband comprising one or more wavelengths selected to elicit a spectral response from a tissue;
one or more image sensors each comprising a pixel array for sensing electromagnetic radiation; and
a controller in electronic communication with the emitter and the one or more image sensors;
a rotation sensor for sensing rotation of the handpiece unit and/or the endoscope;
wherein the one or more image sensors sense reflected electromagnetic radiation in response to pulses of reflected electromagnetic radiation from the emitter to generate a plurality of exposure frames, and wherein the plurality of exposure frames comprises a mapping exposure frame and one or more of a spectral exposure frame or a fluorescence exposure frame.
