Abstract:
The present disclosure relates to systems and methods that facilitate compliance of a laser device with a laser safety threshold. An example method includes receiving, from a sensing circuit, an operating voltage that is indicative of a charge of a capacitive element of a laser pulser circuit. The method also includes comparing a first voltage indicative of the operating voltage and a second voltage indicative of a reference voltage. The method additionally includes providing an output value based on the comparing. The method yet further includes evaluating compliance with the laser safety threshold based on the output value.
