Claim One:
1. An illumination system for use in an endoscopic device having a rapid duty cycle, the system comprising: a laser source comprising a plurality of laser bundles, wherein each laser bundle comprises a plurality of laser light emitters, wherein the laser source sequentially pulses electromagnetic energy in a plurality of individual electromagnetic partitions; a fiber optic cable; an electromagnetic sensor embedded within the laser source to sense electromagnetic energy emitted from at least one, but less than all, of the plurality of laser light emitters within each of the plurality of laser bundles; and a control circuit in electronic communication with the electromagnetic sensor and the at least one of the plurality of laser light emitters, wherein the control circuit is configured to cause the laser source to pulse electromagnetic energy between readout periods of non-optical black pixels of an image sensor; wherein the electromagnetic sensor receives electromagnetic energy from at least one of the plurality of laser light emitters, and wherein the electromagnetic sensor measures an amount of electromagnetic energy generated by the at least one of the plurality of laser light emitters; wherein the control circuit controls a duty cycle of the plurality of laser light emitters based on a predetermined, known output and in response to signals generated by the electromagnetic sensor that correspond to the amount of electromagnetic energy generated by the at least one of the plurality of laser light emitters to obtain a desired exposure response for images captured by the image sensor.
