Abstract: A system is disclosed which includes a laser which has a calibrated optical power and a calibrated tolerance. The system includes a driving circuit configured to generate a first current pulse and a second current pulse. The system includes a primary observer module configured to observe a first and second primary input. The system includes one or more secondary observer modules configured to observe one or more first and one or more second secondary inputs. The system includes a controller communicatively coupled to the laser, driving circuit, primary observer module, and the one or more secondary observer modules. The controller is configured to receive an information packet, calculate an optical power, determine a deviation of the optical power from the calibrated optical power, compare the deviation with the calibrated tolerance, and perform an action if the deviation exceeds the calibrated tolerance.
