Driving light emissions according to a jitter specification in a multispectral, fluorescence, and laser mapping imaging system

A system comprising:

• an emitter for emitting a plurality of 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 plurality of pulses of electromagnetic radiation emitted by the emitter comprises one or more of:
• a plurality of spectral pulses for eliciting a spectral response from a tissue;
• a fluorescence excitation wavelength of electromagnetic radiation;
• or
• a mapping pulse for generating mapping information;
• wherein the jitter specification varies according to a clock frequency of the image sensor;
• and
• wherein the controller comprises one or more processors for executing instructions stored in non-transitory computer readable storage medium, the instructions comprising:
• determining whether the jitter specification has a duration exceeding a threshold;
• and
• in response to the jitter specification having a duration exceeding the threshold, causing the driver to limit a time duration of each of the pulses of electromagnetic radiation emitted by the emitter such that a pulse of electromagnetic radiation does not overlap a readout period of the image sensor.
