1. A system comprising:
an emitter that emits pulses of electromagnetic radiation, wherein the emitter comprises a plurality of sources of electromagnetic radiation, and wherein the plurality of sources comprises:
a first source that pulses electromagnetic radiation within a first spectral waveband comprising from about 513 nm to about 545 nm;
a second source that pulses electromagnetic radiation within a second spectral waveband comprising from about 565 nm to about 585 nm; and
a third source that pulses electromagnetic radiation within a third spectral waveband comprising from about 900 nm to about 1000 nm;
an image sensor comprising a pixel array that accumulates electromagnetic radiation, wherein pixel integration data for the pixel array is read out during a readout period of the image sensor;
a controller in electronic communication with the emitter and the image sensor; and
a driver that drives emissions by the emitter based at least in part on a jitter specification, wherein the jitter specification comprises unpredictable time variation experienced by a component of the system.
