1. A system comprising:
an emitter comprising a plurality of sources of electromagnetic radiation, wherein the emitter cycles the plurality of sources on and off according to a pulse cycle pattern, and wherein the plurality of sources comprises:
a visible source that pulses visible electromagnetic radiation within a first visible waveband that is 40 nm wide or less; and
an infrared source that pulses infrared electromagnetic radiation within a first infrared waveband that is 40 nm wide or less;
an intensity sensor that measures an intensity of electromagnetic radiation emitted by the emitter;
an image sensor; and
a controller in electronic communication with the emitter, the image sensor, and the intensity sensor, wherein the controller comprises one or more processors executing instructions comprising:
receiving an intensity value from the intensity sensor indicating an amount of energy emitted by the emitter;
determining whether the intensity value is within a tolerance threshold with respect to a desired energy output for a corresponding pulse in the pulse cycle pattern; and
in response to the intensity value not being within the tolerance threshold, adjusting one or more of a pulse intensity or a pulse duration for at least one future pulse in the pulse cycle pattern;
wherein the controller synchronizes timing of the pulse cycle pattern of the emitter with a corresponding sensor cycle of the image sensor to generate a plurality of exposure frames;
wherein the plurality of exposure frames comprises a color exposure frame and one or more of a spectral exposure frame, a mapping exposure frame, or a fluorescence exposure frame.
