1. A system comprising:
an emitter for emitting pulses of electromagnetic radiation;
an image sensor comprising a pixel array for sensing reflected electromagnetic radiation;
a controller in electronic communication with the emitter and the image sensor; and
a driver for driving 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;
wherein at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises one or more of:
a plurality of multispectral pulses of electromagnetic radiation for eliciting a multispectral response from a tissue;
a fluorescence excitation pulse of electromagnetic radiation that causes a reagent to fluoresce; or
a pulse of electromagnetic radiation for producing mapping imaging data;
wherein the jitter specification comprises one or both of:
a time delay between a control signal causing the emitter to emit a pulse of electromagnetic radiation; and
a time delay between a control signal turning off the emitter and ending a pulse of electromagnetic radiation;
wherein one or both of the time delays is less than or equal to about 10% of a time duration of the readout period of the image sensor.
