Classification: CPC A  G | IPC A  G

Claim 0:
1. A system comprising:
an emitter for emitting pulses of electromagnetic radiation, wherein the emitter comprises a first emitter for emitting pulses of a first wavelength of electromagnetic radiation and a second emitter for emitting pulses of a second wavelength of electromagnetic radiation;
an image sensor comprising a pixel array for sensing reflected electromagnetic radiation; and
a controller in electronic communication with the emitter and the image sensor;
wherein the image sensor is configured to generate a plurality of exposure frames, wherein each of the plurality of exposure frames corresponds to one or more pulses of electromagnetic radiation emitted by the emitter;
wherein the emitter actively pulses electromagnetic radiation during a blanking period of the image sensor when active pixels of the pixel array are not being read; and
wherein at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises a fluorescence excitation pulse;
wherein at least a portion of the plurality of exposure frames comprises a fluorescence exposure frame corresponding to the fluorescence excitation pulse;
wherein the controller instructs the emitter to vary a duration, or a magnitude, or the duration and the magnitude of the fluorescence excitation pulse at a constant display frame rate to vary an amount of electromagnetic radiation received by the pixel array to control resolution of the fluorescence exposure frame.
