Claim 0:
1. An endoscopic system for use in a light deficient environment comprising:
an emitter that emits a plurality of pulses of electromagnetic radiation for illuminating a surgical scene;
an image sensor comprising a pixel array that senses reflected electromagnetic radiation, wherein the image sensor is disposed within a lumen of an endoscope;
a rotation sensor that detects an angle of rotation of the endoscope; and
a controller in electronic communication with the emitter and the image sensor;
wherein at least a portion of the plurality of pulses of electromagnetic radiation emitted by the emitter comprises:
a first multispectral emission comprising electromagnetic radiation within a first waveband; and
a second multispectral emission comprising electromagnetic radiation within a second waveband;
wherein the first waveband is different from the second waveband;

wherein the image sensor senses the reflected electromagnetic radiation to generate a first multispectral frame in response to the emitter pulsing the first multispectral emission;
wherein the image sensor senses the reflected electromagnetic radiation to generate a second multispectral frame in response to the emitter pulsing the second multispectral emission;
wherein the controller is configured to synchronize timing of the pulses of electromagnetic radiation during a blanking period of the image sensor; and
wherein at least one of the first waveband or the second waveband is selected to identify one or more of a tissue condition, a tissue type, a disease, a biological process, or a chemical process.
